Mozilla removes Do Not Track from Firefox and suggests alternative, but there is a better one

Posted on by Martin Brinkmann

Mozilla plans to remove the Do Not Track feature from Firefox. The idea behind it was simple: inform websites that the user of the browser does not want to be tracked.

What looked good on paper did not work well in the real world. Many sites ignored the header, which made it ineffective as a privacy tool.

Mozilla confirmed the removal of Do Not Track on its bug tracking website.

Global Privacy Control is the alternative

Global Privacy Control was created by several companies in 2020 as a successor to Do Not Track. The core difference to Do Not Track is that it is designed to be mandatory instead of optional, at least in some regions where consumer laws are in place.

Firefox users may enable the feature in the following way:

  1. Select the Menu button and then Settings.
  2. Switch to Privacy & Security.
  3. Check “Tell websites not to sell or share my data” under Website Privacy Preferences.

Is there a better alternative?

Whether advertisers, Internet sites, marketing companies, or other companies and services that track users honor the new Global Privacy Control feature is not in the control of the individual user.

Yes, some companies may get sued if they do not, but there is a good chance that this won’t reach mass adoption in the coming years and that tracking continues to take place.

That leaves taking care of tracking as good as you can by yourself. In fact, installing a content blocker and disabling third-party cookies are two of the best options in that regard.

While you could do more, these methods alone will block the bulk of tracking that you would otherwise be subject to on today’s Internet.

So, pick uBlock Origin and install it in a browser that is not operated by a multi-billion Dollar company. Then, open the Settings of the browser and disable third-party cookies.

Note: in some rare, very rare, instances, third-party cookies may prevent functionality on a low number of websites. If that is the case, you may still set exceptions for these sites while keeping third-party cookies blocked for every other site.

Now it is your turn. Do you enable privacy features such as Do Not Track or Global Privacy Control? What do you to block tracking on the Internet?

Firefox downloads and installs faster on Linux thanks to a recent change

Posted on by Martin Brinkmann

Linux users who download Firefox from Mozilla to install the browser on their device will experience quicker downloads and installs going forward.

Mozilla explained on its Nightly website that it switched the packaging to .tar.xz from the previously used .tar.bz2 format.

The change has the following benefits:

  • The average file size of Firefox is 25 percent smaller.
  • The new format offers improved decompression speeds.
  • Improved compatibility.

A 25 percent reduction in file size reduces the time a download takes. Combined with faster decompression of the new format, it means that Linux users will be able to start using Firefox earlier than before.

Linux users who want to give this a try can check out the change on the Firefox Nightly download page. The download of Firefox for Linux is offered as a .tar.xz package.

The change will roll out to Firefox Beta and Release channels in the coming weeks. Maintainers should take note of the new format and update scripts that they may be using to handle both package formats or start using .tar.xz exclusively.

Mozilla says that it made the decision to use .tar.xz instead of .zst on Linux because the selected format offers better compression. The format is in wide use as well and has no extra dependencies.

Users interested in the development can check out the main listing on Bugzilla.

Mozilla celebrates Firefox’s 20th birthday with a video that teases upcoming features.

Posted on by Martin Brinkmann

Mozilla has published a video to celebrate the 20th birthday of its Firefox web browser. The video showcases some of the existing features of the web browser and also upcoming features.

As far as new features are concerned, there is none that has not been mentioned before. Still, it is a good opportunity to see these features in action in the video. It is only a minute in size.

Here is the list of features that Mozilla teases in the video:

  • New Firefox profile manager and profile customization options.
  • Improved sidebar customization options.
  • Creation and management of tab groups.

The two big upcoming features are support for tab groups and the improved profile manager. All Chromium-based browsers support tab groups already. They may be used to improve tab management.

I use tab groups to differentiate between different tasks for the most part. What I like is that I can collapse tab groups so that an entire group takes up little space in the browser’s address bar.

Yes, some prefer to use bookmarks or other means to keep an eye on tabs. That is perfectly fine as well. Tab groups do not take anything away from that, but they add an option for users who like them.

Firefox Profiles gets an upgrade

The second feature improves the accessibility of the profile manager in Firefox. While Firefox supported profiles for a very, very long time, it was never put right in front of the user like in Chrome or Chromium.

Again, not ever Firefox user uses profiles. One reason for that is likely that it is difficult to find out about profile support in first place. You can stumble upon profiles in Firefox or on the Web, but there is a good chance that many Firefox users do not know about this feature at all.

If done right, this could be an introduction to profiles for lots of Firefox users.

I have to admit that I do not use profiles. I see their use, but I switch between so many browsers that these browsers are somehow like different profiles that I use. But, some users will certainly find this helpful.

What is your take on 20 years of Firefox and the features that Mozilla is teasing. Is this something you are looking forward to? Feel free to leave a comment down below.

Firefox 131 ships with Tab Previews, Temporary Permissions, and other usability improvements

Posted on by Martin Brinkmann

Mozilla released a new version of the Firefox web browser today. Firefox 131.0 is the new stable version of the browser. It is available for all supported operating systems and introduces several new features and improvements.

The details:

  • Site permissions may now be granted temporarily to sites.
  • Firefox displays previews when hovering over tabs.
  • Firefox Translate supports Swedish.
  • Links to text snippets on websites can now be shared.
  • Security fixes.

Firefox 131.0: new features

Temporary permissions

Firefox temporary permissions

Firefox is not the first web browser to support temporary permissions, but it is still a welcome feature. The main idea here is to allow sites access to certain features only for the session by default.

You can still enable permanent permissions. This can be useful if you use a website or app regularly and do not want to be bothered by permission prompts each time you open it.

Firefox permanent permission

Firefox revokes the permission automatically after one hour or when the tab is closed. A click on the site icon reveals whether permissions are temporary or permanent.

Tab Previews

Firefox Tab Previews

Tab previews have finally arrived in Firefox 131.0. Just hover over any open tab in the Firefox web browser and you will get a visual preview of the site or app.

You also see the page title and domain name in the preview. Previews work for local and public pages in Firefox.

Firefox users who do not like the feature can turn it off easily:

  1. Load about:preferences#general in the address bar.
  2. Scroll down to the Tabs section on the page that opens.
  3. Uncheck “Show an image preview when you hover on a tab”.

Firefox will only show the page title and domain name from now on.

Linking to text fragments

This feature allows you to link to specific text on a webpage. There does not seem to be a context menu option yet for this, which makes it a bit hard to create this type of links.

To link to text, append #:~:text=TEXT to the address and replace TEXT with text that you want to link to on the page.

Note: Firefox will always pick the first instance of that text on the page. You may need to be specific, if multiple instances of the text are on the page.

Example: https://chipp.in/software/qbittorrent-5-0-is-now-available-with-a-massive-list-of-changes/#:~:text=qBittorrent%205.0

This address highlights the first instance of qBittorrent 5.0 on the linked page.

Check out Mozilla’s detailed instructions for using the feature here.

Tab Group in Firefox

Firefox is getting Tab Groups – and you may try the feature already

Posted on by Martin Brinkmann

Tab Groups is a useful browser feature that allows you to group open websites together for better management. Most Chromium-based browsers support Tab Groups, as Google implemented them in Chromium and Chrome.

That’s one of the advantages of using an established browser source that is developed constantly. Don’t get me wrong, there are also disadvantages, like the death of Manifest V2 extensions support, which Google put into Chromium.

It is interesting to note that Mozilla introduced Tab Groups into Firefox at a time when Chrome and Chromium-based browsers did not really support it. Called Panorama, Mozilla launched it in 2010 as a way for users to group tabs.

While the implementation was not as elegant as what Google introduced in Chromium and Chrome, it was nevertheless a useful feature to some. Firefox extensions like TabGroups Manager would improve accessibility and usability. Mozilla decided to kill tab groups in Firefox eventually.

A few months ago, Mozilla announced that it would listen to feature requests from the community. Next to vertical tabs, Firefox would also get support for tab groups.

Tab Groups in Firefox Nightly

Firefox Tab Groups Enable

First bits of code have now landed in Firefox Nightly.

Note: Tab Groups in Firefox is not feature-complete at this point. There is no point in criticism Mozilla at this point, as development is still ongoing.

With that said, Firefox users who want to follow the development may enable Tab Groups in Firefox in the following way:

  • Make sure that Firefox Nightly is up to date (check Menu > Help > About Firefox Nightly).
  • Load about:config in the browser’s address bar.
  • Search for browser.tabs.groups.enabled.
  • Click on the toggle icon to set the value to true.
  • Restart Firefox.

Right-click on a tab and select “Add tab to new group” to create a new tab group in Firefox. You can drag & drop tabs between groups already. Some features, such as the ability to collapse and expand groups, are not implemented yet.

What is your take on tab groups in Firefox? Do you plan to use the feature once it lands? Feel free to write a comment down below.

Mozilla removes Adjust marketing integration from Firefox Mobile

Posted on by Martin Brinkmann

Mozilla has used Adjust in Firefox for mobile products for years for a very specific purpose: to determine if the installation of the mobile browser originated from an advertising campaign.

In other words, Adjust helped Mozilla track conversions of its advertising campaigns. It also send anonymous usage summaries occasionally, according to Mozilla.

Starting in Firefox 129.0.2 for Android and iOS, Adjust appears no longer integrated in the Firefox browser.

When you check Settings > Data Collection after upgrading to the latest version, you will notice that the Adjust option is no longer listed.

Firefox Mobile Adjust Marketing
Left side: Firefox with Adjust. Right side: Latest Firefox without Adjust

The Marketing data option is no longer available. It allowed Firefox users to enable or disable the sharing of usage data with Mozilla.

Mozilla did not mention the removal in the official release notes. It is therefore unclear why it has been removed, if you just look at the changelog.

Bugzilla listings confirm that this has not been done in error. Bug 1913363, for example, confirms the removal of the “metric service” and the toggle in Firefox. (via Sören Hentzschel)

Closing words

The removal addresses a major issue that some users have with Firefox: that the browser’s defaults are not ideal for a browser that strives to protect the privacy of users.

With Adjust gone, there is one less thing to worry about in this regard.

0.0.0.0 Day: decade-old vulnerability affects all browsers

Posted on by Martin Brinkmann

Security researchers have disclosed a vulnerability that affects all modern browsers. What makes it particularly worrisome is that it has been known for 18 years; that goes back to a time before Google even thought of creating Chrome.

The details:

  • The researchers call the issue 0.0.0.0 Day.
  • It allows malicious websites to interact with services that run on the local network.
  • This could lead to unauthorized access or remote code execution attacks on local services from outside the local network.

In other words: the security issue allows the circumvention of security protections by malicious websites. Chromium’s Private Network protection does not protect against this, neither does Firefox. Apple’s Safari browser was also vulnerable, but the company has released a patch that blocks access to 0.0.0.0.

The blog post provides a technical description of the vulnerability. It also explains why it took this long to react on it.

The researchers found a Mozilla bug listing that dates back 18 years. It shows that the developers were not sure whether the reported bug was a security issue, a bug, or no flaw at all.

How Google, Mozilla, and Apple plan to react

Researchers at Oligo disclosed the vulnerability to security teams of major browsers in April 2024.

  • Google: plans to block access starting in Chrome 128 and finalize the rollout by Chrome 133. Other Chromium-based browsers will get this as well.
  • Apple: has implemented a change that blocks destination host IP addresses, if the IP is all zeroes.
  • Mozilla: fix is in progress. Firefox is special, as it never restricted Private Network Access in first place. Will implement Private Network Access, but no ETA on this one.

The fixes are important, but so is standardization of the issue. HTTP requests to 0.0.0.0 should be added to security standards according to the security researchers.

Closing Words

The security researchers note that use of 0.0.0.0 on the Web is on the rise. They use counters provided by Chromium for this. According to those, it is used by 0.015% of all websites. While that may not sound like much, it equates to roughly 100,000 public websites that may communicate with 0.0.0.0.

Malicious actors may exploit the issue in their attacks. Oligo points out that ShadowRay, a recent attack that targets AI workloads, could be executed from browsers using 0.0.0.0 as the attack vector.

It is unclear if browser extensions such as Port Authority for Firefox provide protection against this kind of attack.

What is your take on this new vulnerability? Seems that there is always something new, or shall I say old, that is affecting the security of browsers. (via Born)

Zen Browser

Zen Browser: first look at new open source Firefox-based browser

Posted on by Martin Brinkmann

Recently, there has been a bit of a revival when it comes to forks of the Firefox browser. After Mullvad Browser, it is now Zen Browser that is trying to win the Internet by storm.

The Firefox-based browser is available as an alpha at the time of writing. Despite that, it felt very stable during tests.

The details:

  • Zen Browser is available for Windows, Linux, and macOS.
  • The browser is open source.
  • You can download an installer or a portable version.

Since it is based on Firefox, it shares many of its features with Mozilla’s browser. This includes most of the interface and settings, as well as support for extensions. The interface looks modern and clean.

Here are core differences to Firefox:

  • Tabs are displayed on the sidebar and not horizontally.
  • Split view support to display multiple sites at once.
  • Improved profile management controls.
  • Tab Groups support (coming soon)
  • Telemetry disabled by default.

There may be more. Feel free to leave a comment down below if you spot any other.

Using Zen Browser

Firefox users will feel at home when they use the browser. They can import browsing data and install Firefox add-ons in Zen Browser.

Chrome users who think Firefox looks dated may give the browser a try as well, especially since Chrome is soon disabling old extensions like uBlock Origin.

A core difference is that tabs are displayed on the sidebar on the left. There does not seem to be an option to move tabs to the classic horizontal position. Maybe that is coming at a later point.

The settings include a compact mode, which auto-hides the sidebar and displays it on hover. You may furthermore hide the top title bar as well in that mode.

Another option available is to make the URL bar floating when selected. This moves it to the middle of the browser window automatically.

The New Tab page displays just a search option by default. You can add recent shortcuts and Internet shortcuts with a click on the customize button. There is also an option to enable three types of wallpapers: solid color, abstract, or photos.

A sync feature is also available, which requires creation of an account. Major browser features, such as password management, spell checking, translations (via Firefox Translations), or Developer Tools, are also supported.

Closing Words

Zen Browser is updated regularly right now, but it is still an alpha that is in development. Most users may want to wait for the first stable release to give this browser a try, if they are interested in it.

Another thing that may need improving is that the website reveals little about the team behind the browser. While that is not always a necessity, it would improve trust in the project if that would be made clearer.

All in all, a browser to put on the watchlist to check out again in the future.

Keep on blocking in a free world: how to switch from Chrome to Firefox

Posted on by Martin Brinkmann

Google Chrome users who have extensions installed may soon have some or even all of their installed extensions disabled by Google.

While all browser extensions may be impacted, it is ad blockers and privacy extensions that are impacted the most.

One example: uBlock Origin, arguably the most loved and powerful content blocker available for browsers, will not be offered anymore for Chrome and all other Chromium-based browsers.

This means that you cannot install the browser extension anymore in Chrome, Microsoft Edge, Vivaldi, Opera, and myriads others.

One exemption: Brave Software revealed recently that it plans to continue support for uBlock Origin. This would be the one exemption at the time of writing.

The developer of uBlock Origin has created a lite-version of the extension. Called uBlock Origin Lite, it remains available for Chrome. Its functionality is reduced, however.

Furthermore, users of Chrome who use uBlock Origin need to download and install uBlock Origin Lite manually. A click on the “find alternative” button in Chrome

How to find out if you are impacted by the change

Chrome Extensions Support
Google Chrome highlights extensions that will soon no longer be compatible with the browser

Do the following to find out if extensions that you have installed in Chrome are impacted:

  • Load chrome://extensions/ in the browser’s address bar. You may also open the page manually by going to Menu > Extensions > Manage Extensions.
  • If you see “These extensions may soon no longer be supported” at the top, you are affected by the change.

Tip: you can check out a detailed guide about this here.

Google lists all incompatible extensions. Each features a “find alternative” button, which opens a special page on the Chrome Web Store that highlights extensions that continue to remain compatible with Chrome in the future.

For uBlock Origin, Google suggests the following options:

  • uBlock Origin Lite
  • Adblock Plus
  • Stands Adblocker
  • Ghostery Tracker & Adblocker

While all block ads, none offers the functionality of uBlock Origin.

What you can do about it

You have just a few options at this point:

  1. Keep on using Chrome until Google disables the extensions. You may then extend support for about a year using Enterprise policies.
  2. Keep on using Chrome and use a different browser extension that works for you, hoping that Google does not introduce any other changes in the future that may impact it.
  3. Switch to Brave Browser. This is a valid option only if you want to keep on using uBlock Origin, AdGuard, uMatrix, or NoScript.
  4. Switch to Firefox or a Firefox-based browser. The extensions, including uBlock Origin, remain available and maintained for Firefox.

The first option is valid for all Chromium-based browsers, but it is temporary only. Google will remove the Enterprise policy next year, and that marks the end of support in Chrome.

As you see, you have a few options only. While you could keep on using a Chromium-based browser, Brave Browser, it is unclear for how long Brave will support the four special extensions.

Admittedly, it is also unclear for how long Mozilla will support the old extensions system. If it sees an uptick in users, as some Chrome users may migrate to Firefox because of the changes Google implements, it could very well be for a long time.

Are you affected by the change? Do you have any extensions that you rely on that would make you switch browsers, if your current favorite would not support them anymore? Feel free to leave a comment down below.

How to disable Firefox’s built-in ad-tracking feature

Posted on by Martin Brinkmann

With the release of Firefox 128 came the integration of a new experimental feature that Mozilla calls Privacy-Preserving Attribution.

The feature is turned on by default, which means that users of the browser need to become active, if they want to disable it.

Mozilla published a support webpage that explains that Privacy-Preserving Attribution is.

Here is the main quote:

Mozilla is prototyping this feature in order to inform an emerging Web standard designed to help sites understand how their ads perform without collecting data about individual people. By offering sites a non-invasive alternative to cross-site tracking, we hope to achieve a significant reduction in this harmful practice across the web.

In other words: sites and advertisers may use the built-in feature for tracking.

Like Google Chrome’s Ad Privacy feature, it is using the term privacy loosely, some would say disingenuously.

Both systems change how users are tracked and call it an improvement to privacy. In the end, it still means that users are tracked. The fundamental difference is that users are no longer tracked on an individual level.

Mozilla says that its new system can only be used by a small number of sites in Firefox 128. The organization does not mention these sites.

How to disable Ad-Tracking in Firefox

Firefox Website Advertising Preferences

For privacy, disabling these features is better than keeping them enabled or enabling them.

Here is how you do that in Firefox:

  1. Select the Firefox Menu and then Settings when the menu opens.
  2. Switch to Privacy & Security on the main Settings page.
  3. Scroll down until you come to Website Advertising Preferences.
  4. Uncheck the box “Allow websites to perform privacy-preserving ad measurement”.

That is all there is to it.

Pro tip: The user preference dom.private-attribution.submission.enabled determines whether this feature is turned on or off. Set it to false to disable it.

Closing Words

It is not without irony that Mozilla’s implementation in Firefox is in fact worse from a user’s point of view than Google’s. Google is prompting users, using euphemistic words, about the ad tracking feature. Mozilla has just enabled the feature without prompting users about it.

Mozilla has recently bought an ad-tech startup called Anonym, which it says is working on privacy-preserving ad technology.
