Rare crash on 84. User reports that they hit it a bit on Arch Linux https://www.reddit.com/r/firefox/comments/kufrlr/firefox_crashing/

Looks like the same as we had in bug 1676882. The fix (updated env_logger with a fix to not panic on errors) landed in 85

85 is released next week. We won't fix this in 84 anymore.
