Basic information
But in my case Firefox never crashes, it just hangs for ~30 seconds sometimes, with its CPU usage stuck to ~24%. (It's a weird type of hanging as well, if I keep clicking, Windows will not realize that Firefox is hanging and will not ask me if I want to close the program. As if to Windows it's still working just fine. But it won't respond to any of my inputs at that time.) (And there really is no recent crash reports in my about:crash page.)
I took note of the PID of the exact firefox.exe process which has the high CPU usage, after it resumed, I went to about:memory to "measure" ram usage, just to see which PID is which, and it's always the "Main Process".
And this problem doesn't seem to happen with any specific website. I watch YouTube a lot, but this problem also happens when I have no YouTube tabs open at all. (Sometimes I could just open a new tab and Firefox hangs again.)

I'm going to close it out because the profile is gone, and the reporter says the issue went away.
