User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.71 Safari/537.36

Steps to reproduce:

I've tested this issue on macOS.

0. Make sure you are not on the latest Firefox version
1. Go to about:profiles and create two new profiles: test1, test2
2. Create a bash script that starts these profiles at the same time:

#!/bin/bash

/Applications/Firefox.app/Contents/MacOS/firefox-bin -P "test1"
/Applications/Firefox.app/Contents/MacOS/firefox-bin -P "test2"

3. Stop all running Firefox instances and run the script
4. Go to about:preferences in both windows, and see that under the "Firefox Updates" section both instances are stuck on the message "Firefox is being updated by another instance"
5. Exit one profile by right-clicking on the Firefox icon in the dock and clicking "Quit"
6. Refresh about:preferences in the other profile, and see that the update process automatically starts

Actual results:

Update process gets stuck on "Firefox is being updated by another instance" if two profiles are started at the same time.

Expected results:

One of the instances successfully completes the updated process, even when both profiles are started at the same time.
