My Firefox tabs crash repeatedly even when I tried opening them in Troubleshoot mode. When I play videos in the browser, there's this stuttering, buzzing noise while the sound lags, too. Usually it's tabs playing YouTube videos that crash, but I've also had tabs crash when I try to open completely unrelated websites. I've disabled hardware acceleration, repeatedly cleared my cache, and even tweaked some of my GPU throttling settings, but nothing seems to help.
