Firefox Version 71.0 is incredibly slow.

Posted

20GB system Ram 8 Core CPU

I run many tabs in my browsing session and have for many years.

Version 71.0 of Firefox is so slow as to be unusable (but the competitor product is still fast)

Thank you, but I am reporting that the new version of Firefox, Version 71 is the problem, it is very slow compared to the prior versions.

The fix that I need is a patch that restores the performance that I enjoyed in the prior versions.
