Escape developer's version in favor of stable without losing profiles

more options

Hello. I use developer's version of ff for a few weeks (currently on 107.0b2). I recently decided to switch back to stable version 106. However, when I run it it says

``` 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. ```

So, how do I move from developer's version back to stable without losing anything?

(OS: debian 11, if it matters)

Solved it with the help of kind redditors. To allow the current profile in lower versions of ff, pass "--allow-downgrade" as argument.

Method 1: Use the Profile Manager wizard Follow the steps in the Profile Manager - Create, remove or switch Firefox profiles article to create a new profile.

Method 2: Manually delete the profiles.ini file If you have problems accessing the Profile Manager, you can create a new default Firefox profile by deleting the profiles.ini file, using these steps:

   Click on the Windows Start button or press the Windows key Windows Key to open the Start Menu.
   Type %appdata% (as you type, a Windows search will start) and press the Enter key. The hidden AppData\Roaming folder will open.
   Double-click the Mozilla folder.
   Double-click the Firefox folder.
   Delete (or rename, for example, to profiles.iniOLD) the profiles.ini file.
