Compared to chrome, firefox is not memory hungry and its great! You should also check out ZuriWeb, a mini web browser on your menu bar. One of the best productivity tools i've used.

I currently have a few browsers installed: Safari Chrome Firefox Edge The two I use the most are Safari, and Firefox. Since I typically don't use a lot of add-ons, Firefox has been fairly stable for me. My main reason for settling on FF as the main browser was cross platform, and the best browser for third party extensions. Safari also works with the few add-ons I use as well. However, with Safari, I've run into certain sites, that don't always play nice like they do in Chrome, or Firefox. With Edge, I installed it to test it when it was first released for the Mac. The site compatibility issues with Safari have lessened as Safari has matured over the years, and as of Big Sur finally supports full YouTube video quality resolutions like Chrome, and Firefox.

CSS code for Tabs On Bottom (under the bookmarks bar) for Firefox 89 & 90 is available here: https://www.reddit.com/r/FirefoxCSS/comments/nq2d0q/tabs_on_bottom_for_firefox_89/ Once again, this long-time FF user has to wonder why Tabs On Bottom isn't a simple preference choice, for which I would GLADLY PAY for Firefox, but only the wizards at Mozilla (who've spent millions on rather useless things like "Pocket") know the answer to that. -SB

The update to 89.0 proceeded just like any other update. I was concerned about the new schemes, as none looked inviting. However, I was immediately offered to keep my previous scheme, which configured just fine. (thumbs up!). I otherwise use minimal configuration changes. I continue to prefer it over Safari ,and Firefox's efforts to keep browsing, etc. more secure. Still using OS 10.12 and have no issues with using it on a large screen.

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.
