You don't have to do anything. K-9 Mail remains K-9 Mail. A mistake was made in the naming process. This will be fixed soon. So in F-Droid the following will be present: K-9 Mail Thunderbird Thunderbird Beta

Thunderbird for Android is based on K-9 Mail, but has received a few changes here and there (e.g. the accent color is blue instead of pink). As mentioned above, K-9 Mail will remain and will probably continue to get the Beta & Stable versions in the version selector. Thunderbird has been split into two apps for this purpose. The settings should usually be able to be adopted from K-9 Mail and vise versa, because of the same codebase (but I haven't tested it). In the end, it's up to you whether you prefer the dog or the bird. :)

Edit: Added more info.

If the problem doesn't come from an add-on, it's best to download Firefox from the Mozilla server for your system in your language and see if it's there. This version is then shielded from the other Firefox installation and is like a new installation of Firefox. Also you can then narrow down the problem and see if there is a problem with your current Firefox installation or if it is due to something else.

I have the tag function as in the picture in 132. Do you use any add-ons that have something to do with bookmarks? I couldn't find an option that affects this either. Not even in about:config.

I found 3 solutions, all of which have the same solution. You should enter a bookmark tag in the Bookmarks Manager so that this appears. It's probably a bug since Firefox 116. Solution 1, Solution 2, Solution 3.

Now it remains to be seen whether it will work for you.

Edit: Have linked solutions.
