Orbit by Mozilla is a browser extension that brings AI-functionality to Firefox. It was announced in September 2024 and is currently available as a beta.
Orbit supports a few options right now, but there are also limitations. As far as these are concerned, it is available only for pages in English at the time of writing.
Main features include:
- Getting a quick summary of a webpage’s or a video’s content.
- Interact with the AI in a chat-like interface.
What about privacy?
Mozilla says that Orbit does not use user data for training. It is based on Mistral 7B, which is one of the top small large language models out there.
The service does not require an account, which is good for privacy. Downside is that prompts are lost when you navigate away from a page.
Mozilla states in the privacy policy that is is getting information when the service is used.
We receive basic telemetry data by default, which we use to improve the performance, stability, and security of the Service, including information about your device, including hardware configuration and device operating system; browser information, such as browser type and settings; log files and usage data; and event information, such as errors or crashes. We may also receive additional information about your device, such as country, language, operator and OEM, which we use to prevent fraud and abuse, enforce our terms, and improve the security of the Service.
Orbit uses third-party services and shares some information with those. It uses the Google Cloud Platform as well as Sentry for application performance monitoring.
Using Orbit

First thing you do is install Orbit in Firefox. You get a privacy prompt after installation. Here you select whether you want basic telemetry to be shared only or more.
Once that is out of the way, you see the Orbit icon floating in the right corner of webpages. Hover over the icon to display the available actions. The top two, Summarize and Ask Orbit, are the main actions.
Summarize provides a short summary of webpages, emails, videos, and other content on a specific site. It is designed to return the essence of the page, but it may be too basic, especially on longer pages, emails, or videos.
The ask Orbit option is available as a standalone option and also after summaries. It works like other AI chat tools. Type a query and wait for the AI to respond.
The option works well with summaries. Start with a summary and then ask Orbit for additional details.
I tried this on several videos, and it worked really well (using transcripts). Orbit answers follow-up questions that you may have, and it worked surprisingly well in tests.
You may also chat directly with Orbit. Chats are limited to content on the active webpage. This limits Orbit.
Closing Words
Orbit, all in all, is an interesting helper extension. While it shares issues with every other AI-tool out there, mainly hallucinations, it is designed to help users make sense of content that they see in front of them.
It worked well with videos, especially with follow-up questions. Still, it may be necessary to verify the information that the AI provides, especially if it is critical.
