So moz://a (Mozilla) decide to kill its own browser with a so bad UI : too big ! Previous version was more slim, a comfort with wide screens ! Use instead firefox ESR ;-) (the long time support for entreprise) https://www.mozilla.org/firefox/enterprise/

Not liking 89 at all the dark theme is too dark and the light theme is too bright so i tried to go back to 88 and was greeted with a message that I had to create a new profile in order to go back. Think I will just use Safari its much faster anyway, I see why Firefox is losing users.

Since the update to v89.0 it has become boggy and slow on my 2016 (Intel) MBP. Disappointing. I hope it is improved soon!

Firefox 89 totally messes those of us with custom .css configurations, including Tabs on Bottom. Tabs are now showing up on the status bar at the very bottom of the window, and when you click on one, all the rest disappear, rendering the browser non-functional. So I've gone back to version 88 until some guru can sort out the code necessary to get the functionality back. I've long since given up on Mozilla coming to its senses and actually listening to users, but as long as the product remains configurable, I'll continue to use it. It's still the best, safest, most secure browser in Macdom and I would gladly PAY Mozilla for Firefox. Revenues from Google are probably still keeping the company afloat, although their boat is probably springing more leaks with each passing release. -SB

Make sure to checkout Firefox 89. Loving the new UI and the browser overall feels much more native on macOS - awesome work Mozilla.
