EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.
