Looks right. Then you don't have to do anything. I mean, it's up to you, but do you really want to continue using the beta?

It's easy to find out. Navigate to Thunderbird Beta in F-Droid Basic and look at Versions. If you only have a single version there, then you have to delete it. If it says that no version with a compatible signature was found, so too. If you have three versions to choose from and one of them is installed, then you don't need to do anything, because then you will get updates.

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.

Here you go. More.

Unfortunately, it is broken and there is an issue about it on GitHub.

Ok, that's really strange. The others seem to have the same problem with different solutions, which doesn't work for everyone. That's why I would suggest opening a new issue on GitHub. And post the link below your post so that others can contribute.

Maybe it's because of GraphenOS? I tested it on Android 13 Vanilla (Nokia X1) with Voyager 2.17.1 (F-Droid) and Swiftkey 9.10.44.22 and it works. Are you also using version 2.17.1? Did it work with 2.17.0?

What device do you have? Do you have Android Vanilla / Android from the manufacturer, or do you have a Custom Rom? Sorry for the stupid question, but you only mentioned two keyboard apps. Have you tried other keyboard apps, for example Fossify Keyboard? Where did you get Lemmy from (Google Play, GitHub, F-Droid)?

There is the FinTS option, which I think only works in Germany. Accordingly, unfortunately I can't help you. :( I hope someone else can help you and you will find what you are looking for.

You're welcome. :)
