So I recently installed Firefox beta. It installed on top of main firefox. Now I am in beta version 84 but if i try to open regular firefox release version 83 it says running an old version will corrupt profile data. It just has an option to create a new profile, so i am asking if there is a way to import my settings from my original profile or make my original profile run on version 83 or should I just wait for version 84 to be released in main firefox.

After the above, use sync to share data between each profile. Note: Some data can not be shared between versions.

We recommend: When using different types/versions of Firefox on one system, that you use a different profile for each one. This is because of compatibility issues.

Leave beta alone for a moment. Open the non-beta but use this command to create a new profile.

Usage: C:\PROGRA~1\MOZILL~1\firefox.exe [ options ... ] [URL]
      where options include:

-ProfileManager Start with ProfileManager.
