Firefox crashes on various occasions. Often when I skip through youtube videos, sometimes when just opening youtube videos. Sometimes on non-multimedia-sites. Flash is not installed.

As your using nvidia drivers please set in about:config the following options,

layers.acceleration.force-enabled
webgl.force-enabled

both to false and retest.

After a quick review of code, it looks to be a mesa issue. Please provide mesa version.

Do you have the custom-cflags / custom-optimization use-flags set? I had crashes in similar scenarios. When using the default optimizations/cflags, i still have crashes, but only once in a while instead of constantly.

No, just CFLAGS="-march=native -O2". I didnt touch these configs for years.

If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system.
