The Problem: I recently noticed that decoding youtube videos in 2160p60fps is choppy beyond recognition.

Diagnose: While playing said videos in firefox i was able to observe in the task manager that actually none of my graphics cards video decoding capabilities were used. At lower video qualities/resolutions the hardware accelerated video decoding of the graphics card was also not kicking in, but in these cases my cpu was still able to cope with the decoding load, so I never noticed the missing hardware acceleration. To narrow the origin of problem down I tried watching the same videos in edge, chrome and even downloaded a short 2160p60fps clip to play with VLC and everything worked fine, just not in my favorite browser firefox :(

What i already did trying to solve the problem (in order): -Restart Firefox without addons -Refresh Firefox -Create a new Profile

Additional Info: Nvidia Driver Version 441.20

If there is anymore useful info I'm more than happy to provide it.

Thanks for taking the time reading this an providing help.

Recently I've been having trouble with the dropdown menus in Firefox, such as the History and Bookmarks menu in the tool bar and the right-click menu. Intermittently when I open the menus they close within a second or two without me doing anything. This only happens in the Firefox window, all of my other apps and browsers are fine.

I'm running on a Macbook Pro with OSX 10.15.1 and Firefox 70.0.1. I've restarted Firefox and it fixes the problem for a short time then the problem returns. I've cleared my History, including Caches and Cookies, reinstalled Firefox, restarted my computer and tried disabling my add-ons. The issue keeps coming back.

Persistent scroll problem on one site following a post-crash session restore

I don't normally save and restore sessions, but do have firefox set to restore the previous session in the event of a crash.

Recently, following a power cut, such a session restore occurred, correctly restoring all the pages I had open at the time (not many), and the scroll position within the page.

Since this happened, any page I open on one particular site (https://www.theguardian.com) now always scrolls to the end of the page, and I have to manually scroll back up to the top. Once loaded, you can scroll the page normally, but F5 refresh will reload the page and scroll to the end again. This effect is persistent across restarts, and I've not found a way to get rid of it.

I've tried simulating another crash with that site open, scrolled to the top, and I've tried enabling saving the session on exit and restoring on startup - none of this has changed anything. In both cases it restored the session and scrolled to the end.

Any suggestions as to where this effect might be coming from?
