I was very surprised, looking into the Firefox package today, to discover that XUL is still there and actually responsible for 75% of the heavy weight of the app! I thought they had removed it when they dropped the old extensions system but apparently Firefox is still relying a lot on it... I couldn't find any information on that. Maybe this is why Firefox is still slower than any Chromium-based browser... Still my browser of choice though. ;-)

Upgrading from 88.x which was pretty good actually, I found that 97 was a regression back to the bad old days of FF. Slow, sluggish windows that take ages to draw their own elements, there is a massive lag in drawing the toolbar every time you hit new Window. Zooming which was perfect before is now jerky and clunky compared to 88.x. FF is always being pulled backwards to its prehistoric crap old ways. FF needs to keep a firm grip on the Mac user experience or it will just lose users to Brave and others. I would rate 88.x as a 4 out of 5 and 97 as 3

how to fix: Open a new Firefox window. Type about:config in the URL bar. This will open a settings screen. Search for the setting ‘network.http.http3.enabled’. Set this setting to ‘false’ to disable HTTP3. Then, fully close and restart Firefox.

Still the slowest browser on Mac (do several speedtests yourself like Speedometer, Jetstream etc.). Safari is the fastest followed closely by Google Chrome. Firefox lags far behind…

Version 96 brings many fixes around WebRTC like "significant improvements in noise-suppression and auto-gain-control as well as slight improvements in echo-cancellation". The other main change is "significantly reduced main-thread load" which hopefully will soon get its own blog post as it is a very important change and will improve the Firefox experience for users despite not being an immediate UI change.

96.0 is out since Jan., 10th. Attention: Firefox 96.0 creates a new profile. All bookmarks and possibly opened tabs will disappear. Problem: Despite deleting all cookies, browser security set to default, and preferred websites entered in "Manage exceptions...", I very often get the message: Redirection failed. Back to FF 95.0.2, which did not have these problems.

More than one glitch running v93.0 with Big Sur: Selection boxes on many websites do not show "✓" or "●" mark. Many websites missing color on text & symbols displayed in earlier versions. Bug report totally non-intuitive & impossible to use.

Good alternative to Chrome and Safari. Another good browser is ZuriWeb, it's a menu bar mini browser that's good for multitasking. It's on the official mac app store.

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.
