Attaching files to Thunderbird via drag & drop

flatpak list

If you see Thunderbird listed there, it's most likely a file permission issue. You can then install something called Flatseal from the software store, and use it to grant exceptions to wherever location that you need in your system:

Updating to the latest software versions? Specifically Rhythmbox v3.4.8?

Flatpak packages can't access the rest of the filesystem by default, so that might be getting in the way of things. You can create a rule allowing specific Flatpak packages access to certain files, however, using something called Flatseal (available in Software Store): [sc1] Scroll down to Filesystem and either enable All user files, or specify the file to the location that you need. From what I've seen plugins should be stored in /home/zenzen/.local/share/rhythmbox so that's what I'd sugges…
