joluveba I downloaded the Firefox Beta 108 appimage, I did some configuration (the same extensions I used in my Firefox eopkg), I opened a few sites, and bang! Frozen again. I have just deleted the appimage.
I cite myself. Despite my disappointing experience with Firefox Beta 108 appimage, I couldn't help myself and installed Firefox 108 from the Unstable repository. Unfortunately, it froze again, but this time I saw an improvement, if I minimized the window, the scrolling worked. Anyway, Firefox 108 didn't solve my problem.
Now, the good news. Firefox Nightly 109 appimage keeps working OK, it hasn't frozen a single time. It's what I'm using to write this post. When it lands in the Shannon repository, I think that my Firefox problem will come to an end.
