Firefox is somewhat randomly freezing upon opening something in a new tab, and on starting afterwards
Seemingly randomly, when opening a new tab, FF freezes up completely.
This has only started happening today. After starting my PC, I opened up FF. Upon opening Dicord in a tab (3rd tab, YouTube and Twitter were previous and still open) and clicking on it while loading, it froze. A white line appeared at the top, and FF overlapped, and thus hid, my task bar. Waiting (5 min) did nothing, so I clicked and the "... is not responding" dialogue popped up, and I closed it.
Upon starting again, it restored the tabs that were previously open. I could swap between use them normally. However, when I opened a link in a new tab, it froze again.
After another restart, not even the new empty tab would load, freezing again, and every try afterwards.
Starting in troubleshooting mode or reseting did nothing (though I may not have waited long enough, an 'Old Firefox Data' folder was created and filled, but no window opened). I ran the installer again, which resulted in me having to redo some Addon settings, but worked fine for a while (~1h maybe?), before freezing again. A PC restart fixed it again for a longer while, but then it happened again, this time while trying to write this. Additionally, there was a freeze while clicking into the Subject field here, after which the even the new tabs froze again.
Another PC restart seems to have allowed me to use FF again, while I tipped this on my phone.
Hardware acceleration is off, History deletes every time I close FF, Addons on or off don't seem to matter. CPU and RAM aren't even near fully used. Drivers are up to date, Windows as well. (Running a System File Check right now, as I have upgraded to Win10 only a few days ago, although I was able to use FF during those days without issue, and the PC has been shut down in between as well. The SFC said it found and repaired files, though it didnt say anything other than that, so that might just be a "We found no issues and fixed those." translation kinda thing.)
I really don't know what else to do.

Well, it didnt happen for a while, though I did restart my PC everyday.
Now, the last 2 days I just used the Hibernate option, I think its called? And just now, it happened again, again when opening Discord, and then once more opening Youtube. It seems to get stuck at "Reading *website*", at least thats what shows in the bottom left during these two freezes.

I have seen two or three reports of problems running Firefox after the computer has been in sleep mode so it may be the same issue.
So, quick update:
Something similar has happened a few more times since my last comment. Namely, the freezes resolve themselves after a few seconds. And the full freezes havent happened again, yet.
I have either fully shut down my PC, or just kept it running, so no sleep or hibernation mode, and I frequently restarted FF.
I am still confused, tbh.
Could it be a memory or CPU issue? EDIT: added some articles about troubleshooting.

I had a similar problem but when I cleared Firefox cache it stopped happening.
