Firefox not working since new version installed

Since I installed the new version of Firefox, it crashes constantly, especially on Facebook.
When I go to Facebook, it is very slow, the posts don’t show up (only 1 or 2) and when I wait for the posts to show up, Firefox closes and files a crash report.
I reset Firefox. It didn’t help.
I re-installed it. It didn’t help.
Can anyone help me? Firefox is my favorite browser. I use it as my default browser. Please help, so I can continue to use Firefox.
I would appreciate any help.
Thank you

Hi! Can you link to a crash report?

What OS? Are the video drivers up to date from the official site?

Does it happen on a new profile? You can create and launch it from about:profiles.

You can also try Firefox ESR. It is older but still supported.
