It'd also be very good if they solved the bug of FF not responding when the CPU is under heavy load. Some agent is doing some random testing work in a VM and suddenly firefox won't load new pages. Happens under both macos and linux.
BTW. The "won't load new pages" may be something else. If an agent launches its own Firefox in a new profile, it will sometimes trigger the auto-update which will overwrite the binary in the profile you were using. It won't crash but you'll get a warning to restart.
It shouldn't even have access to the same binaries you are using but only those within the jail it is running in.
