This appears to happen during media playback, but importantly there's several comments mentioning opening URLs to videos via gmail:

as i want to open a link from my email box gmail and from youtube, if i click, Firefox crashes. I have to slowly copy a link like this: https://youtube.com/shorts/CVrwEJKj7RU?feature=share3 and then past it in the adress bar of a new tab, so it usually don't crash. ?? the end of the link seems unnecessary, but whith or without this end, when i copy, paste, it works well. The critical moment is if I left clik with the mouse or if i rignt click too fast apparently.

just the right click on a ling in gmail seems causing crash

It seems that the crash occurs repetitively as I'm about to rignt click on the link toward any video inside my gmail account.

Was opening a link forward a youtube windows

Indeed several crashes have the URL annotation set to https://mail.google.com

There's a few more video-related ones:
