You’ve just been upgraded to Firefox Nightly 111!

Every 4 to 5 weeks, a new major version of Firefox is released and as a result, the Nightly version increases as well.

This is a good time to thank you for helping us make Firefox better and to give you some pointers to documentation, communication channels and news sites related to Nightly that may be of interest to you.

If you want to know what’s happening around Nightly and its community, reading our blog and following us on Mastodon or X are good starting points!

Want to know which platform features you could test on Nightly and can’t see yet on other Firefox channels? Then have a look at the Firefox Labs preferences page.

Do you experience crashes? Unexpected behavior? Web compatibility regressions? We’d love to get them filed in Bugzilla to make sure they don’t make it to the final release (extra karma if you add the Nightly-community keyword to your bug reports)!

Go community!
