Firefox 138.0.3 fixes two crashes and some other issues

Posted on May 13, 2025May 14, 2025 by Martin Brinkmann

Mozilla plans to release a new point update for its open source Firefox web browser later today. Firefox 138.0.3 is a non-security update that fixes three issues in earlier versions of the web browser, including one crash issue.

If you use Firefox on the desktop only, you may ask yourself if you missed the Firefox 138.0.2 release. You may have, as this special version was only released for Firefox on Android.

Firefox 138.0.3: the fixed issues

Firefox 138.0.3 fixes a WebGL-related crash. Mozilla notes that Firefox could crash when websites that use WebGL were opened. WebGL, which stands for Web Graphics Library, is used to render 2D and 3D graphics using JavaScript.

Web games and other interactive or animated content may make use of WebGL. So, if you ran into crashes while running the recent version of Firefox, there is a good chance that this was caused by the WebGL bug.

The update fixes a second crash. This one occurred on websites where certain SVG effects were applied to very small areas.

Firefox 138.0.3 fixes two additional issues:

  • Videos looked washed out on Linux under Wayland, if HDR was not supported on the system.
  • The keyboard shortcut Alt-C did not work as expected in the sidebar search.

Mozilla has not published the official release notes at this time. The release notes will be published shortly after the Firefox 138.0.3. You can access them here afterwards to check them out.

The new update is only available for the desktop versions of the Firefox web browser. Furthermore, Firefox ESR are not updated, as they appear to be unaffected by the issues.

Mozilla plans to release the next major version of Firefox and Firefox ESR on May 29th, 2025. The following versions will be released on the day:

  • Firefox 139
  • Firefox 115.24 ESR
  • Firefox 128.11 ESR

Now you: where you affected by one or several of the fixed bugs? How do you handle point updates usually? Do you install them right away, postpone their installation, or skip them? Feel free to leave a comment down below.

    Well, I haven’t experienced any crashes, but apnews.com which uses Cloudflare just blocked my access to it. I always use a VPN (Mullvad) and tried changing my IP a few times, but to no avail.

    The Associated News site called apnews.com which I wrote about in my previous post has been given a facelift. I can now access it again, but get a Cloudflare prompt which has a prompt whereby users have to checkmark to proceed further.

    No problem with that except that now that prompt appears when trying to access other articles on the same site during that same session even if the attempt is made within minutes of each other. It quickly becomes tiresome however and after reading just aa couple of articles I left the site altogether.

    I often use tinyurl.com to shorten long links and that same Cloudflare prompt appears on that site too, but only once provided I don’t switch my IP to another one during the same day. I think APNews.com should consider implementing the same action since it’s going to impact AP News traffic stats if the user has to checkmark the prompt again after every article like it is at the moment.

        Well, obviously not.

        People these days post their comments then forget about it, wonder why they do that. Guess, people uses this comment section just to write his own thought for no one but himself.
