recent Firefox updates extremely slow

[cjgiam]

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.
