Prevent company install of older version?
I installed FF 100, and my employer pushed FF 99 over that, so when I started FF, I got the "You launched an older version of Firefox..." and of course the only options are to exit or create a new profile. I assume they did that because of broken sites with 100. Is there a way to prevent that from happening again? And please no lectures. However, FF wasn't even installed by the company. I installed it. The expected (and installed by default, obviously) browser to use is Edge. The next most widely used (also user-installed) is Chrome.

There is a way to set the user agent in Firefox 100 to 99.0 (or any other version) via about:config if that is the reason, so maybe share this option with your IT department.
network.http.useragent.forceVersion = 99.0
https://searchfox.org/mozilla-release/s ... p#line-280
If the "network.http.useragent.forceVersion" pref has a non-zero value,
then override the User-Agent string's Firefox version. The value 0 means
use the default Firefox version.

If you have to live with Firefox 99:
You probably found this by now, but if you still need it:
You can use the "allow-downgrade" workaround described in the following article: https://support.mozilla.org/kb/dedicate ... stallation
Or manually migrate key files to the new profile: https://support.mozilla.org/kb/recoveri ... ld-profile
Or sometimes it works to go into the profile and rename the compatibility.ini file (compatibilityOLD.ini) so Firefox 99 doesn't know who used/upgraded the profile last. (Not a supported option, but it sometimes works.) The method would be:
* Open about:profiles
* Find the profile you want to re-use, and on its Root Directory line, use Open Folder
* Right-click compatibility.ini, click Rename, insert OLD before the dot, then click away or press Enter to save the change
* Back on about:profiles, click "Launch profile in new tab"
* If it works, you can use the "Set as Default" button for that profile, which should take effect at your next startup

Re: Prevent company install of older version?
(If the company pushed 99, then why are they even on a Release version rather then the [91]ESR?)
Fire 750, bring back 250.
