recent Firefox updates extremely slow

cjgiam — Sat, 21 Sep 2024 19:40:35 GMT

Firefox is EXTREMELY slow after last 2 updates. Rendering relatively useless.

I have had to reluctantly switch to Edge.

Firefox has been my 'goto' for years, please fix.

I have done everything but a complete refresh/reinstall (including troubleshoot mode), i don't want to lose my extensions, they are critical to my sessions.

Totally agree - the last updates caused severe slow-downs in identifying URLs and loading them - unacceptual time needed. This is a wakeup-call for the devs! Looking for alternatives. Anything to do with macOS recent updates? Working with MacMini 2018 6-core i7 3,2 - 4,6 GHz 32 GB Main, 512 GB internal Apple SSD. There is always appr. 16 GB free main memory available and CPU-usage down to less than 40 %!

Did you tried creating a new profile? browsing with no extensions and default settings can give you an idea of what is causing the performance issues.

Same here. No good for developing Wordpress anymore. Had to switch to Edge (reluctantly) even though their developer tools are not so good.

I run a couple of websites with MANY links. I used to be able to use a multiple url opener to make sure the links were still valid and had no trouble. Now Firefox won't close as I close the urls, and I have to go to Task Manager and manually close them before starting the next batch. Using bing I can literally go through 3x as many in the same time it takes Firefox just to open them. I don't know what happened to Firefox, but I'm getting tired of it VERY FAST.

Remains Extremely slow for the past 2 or 3 versions. Feels like late 80's 14.4 baud modem. MS edge works fine.
