Firefox 53 Asking to Restart to Update Endlessly
Solution 1:
Firefox's own support pages are finally back online after their migration to Moz://a.
This link explains my issue and offers the correct solution, which is as follows:
- Delete the folder "Mozilla" residing in
/Users/<user>/Library/Caches/
- Restart Firefox.
The dialog should no longer pop up each time the program is launched.
