Firefox has two main release channels:
- Firefox: Simply named Firefox, this is the default channel and is the one recommended. It’s the stable branch with the latest features available. Once a new release is out, the older release immediately stops receiving support and everyone must migrate to the next Firefox release.
- Firefox Extended Support Release (ESR): is an official version of Firefox developed for large organizations like universities and businesses that need to set up and maintain Firefox on a large scale. Firefox ESR does not come with the latest features, but it has the latest security and stability fixes. Usually these branches are supported for a year, with a planned release calendar for new ESR branches. For more information you should review the release cycle documentation.
Firefox also has three testing channels:
-
Firefox Beta: This branch is meant to reflect what the next Firefox release will look
like. Every four weeks it gets cherry-picked changes from Nightly, then follows a three weekly
point release aimed at stabilizing the release for the stable branch. Version number is always
X + 1,Xbeing the Firefox version number. -
Firefox Developer Edition: This branch is based off the Firefox Beta branch with
additional DevTools merged in. It gets released alongside the Firefox Beta release, following
the same release pattern. Version number is always
X + 1,Xbeing the Firefox version number. -
Firefox Nightly: This is the branch that receives all the changes before anything else. It
gets daily updates which represent the master branch. This is the branch that first features new
changes/features, which then may be forwarded to Firefox Beta after being tested. Version
number is always
X + 2,Xbeing the Firefox version number.
Special notes
- Firefox 78 ESR was the last version of Firefox that supported macOS versions < 10.12 or Flash.
- Firefox only supports last 3 macOS releases, matching the Apple support cycle.
More information is available on the Firefox website.
You should be running one of the supported release numbers listed above in the rightmost column.
You can check the version that you are currently using by running:
firefox --version
