Hi.


I hope you can help me to figure out how to upgrade Firefox properly when not using Mozilla Maintenance Service . If I do upgrade Mozilla Firefox manually (running exe installation) or forcing upgrade for thousands computer through Central management, profiles will blow up. 

It is popping for the users:

You've launched an older version of Firefox Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox.

It is not related to central management because I've tried to install manually by executing Firefox exe executable - firstly to install Mozilla Firefox 97.0 and after that 98.0 and I've got the same error.


Thank you

That error only happens if you're downgrading a user. The current version of Firefox is 99, so it sounds like you're pushing 97 or 98 to users that have 98.

You can prevent this error by launching Firefox with the --allow-downgrade parameter or setting the MOZ_ALLOW_DOWNGRADE environment variable to 1.
