While changing profiles, sed Profile wont open and said a Error Message
When i was changing Profiles, Firefox said an error message "Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. For your protection, create a new profile for this installation of Firefox"
Its my first time using Firefox and I'm very Worried. I have a lot of data and bookmarks on that profile. I have 2 types of Firefox, Normal Firefox (Version 91.0.2 64-bit) and Firefox Dev Edition (Version 92.0b9 (32-bit) Normal Firefox for Browsing and Dev Edition for coding. When i was trying to use the Profile in Dev Edition (Pre-made in Normal Firefox) it worked. But when i was trying to use the profile that i used on Dev Edition it doesn't work. Then i was forced to make a new profile.
Can anyone solve this problem? I've never Updated Firefox because i downloaded in Version 91.0.2

You can upgrade a profile, so it is possible to run a Firefox release profile with the DE version. Once you have done this, either deliberately or accidentally, then you can no longer use this profile with an older Firefox version. You always need to be cautious when you use multiple Firefox versions Firefox 92 is about to be released next week (update on DE have been halted and Beta is in release (RC) stage).
