macOS froze completely while youtube videos were playing
October 14, 2021 at 02:11
I'm concerned about the security of my iMac. I left it playing a youtube video and somehow it segued to playing other youtube videos even though I block autoplay of videos and audio. Well, when I tried to stop the video or close the Firefox browser then everything was frozen and when I tried to open other MacOS applications such as Activity Monitor to kill Firefox then everything on my Mac was frozen too!
So quickly I pulled plug to my router but that didn't help so I was forced to restart the computer!
I scanned for malware and viruses using Malwarebytes and ClamXAV though found nothing.
The only thing that I could find that might describe this phenomenon was a post from several years ago that Firefox's hardware acceleration might be responsible.
However, I don't see that setting in Firefox.
My macOS and Firefox and everything else are updated fully.
Can someone explain this? Thank you!
