Description Mauro Matteo Cascella 2022-03-09 12:33:13 UTC 
Previously Firefox for macOS and Linux would download temporary files to a user-specific directory in `/tmp`, but this behavior was changed to download them to `/tmp` where they could be affected by other local users.  This behavior was reverted to the original, user-specific directory. 

*This bug only affects Firefox for macOS and Linux. Other operating systems are unaffected.*
