Problem with firefox browser? Or another problem?

Question

Mozilla Firefox

It happens that I’m looking for something, and firefox falls (or the problem is not in it)
Look at the screenshots and videos and tell me what the problem is and how to solve it?
When looking for a picture, there were still about 10 tabs open

I clicked to end the firefox process (but not completing it), everything fell into place, but after opening another site, this is immediately:

opened another site

and then right away

updated the page again

Although other applications and everything else works
Watch the video (this happens when I just scroll): https://www.youtube.com/watch?v=2rBvx98J21w

Tell me what the problem is and how to solve it
