I installed LibreWolf and Ungoogled Chromium as Flatpaks. But in GNOME Settings, where it shows the default web browser app, it shows Firefox, with no dropdown where other options can be selected. I wasn’t able to find a command line alternative that looked like it would work for Silverblue. Any tips?
Hi, sorry to hear you are having problems. I use both those browsers on Kinoite. Yes, there is a way to set your browser from the command line.
LibreWolf flatpak:
$ xdg-settings get default-web-browser
io.gitlab.librewolf-community.desktop
ungoogled-chromium flatpak:
$ xdg-settings get default-web-browser
io.github.ungoogled_software.ungoogled_chromium.desktop
Try running xdg-settings set default-web-browser [value] with either of those two strings.
strange can you send us or show screen record what it shows when you try to set default in gnome settings
and output of flatpak list
Sure, here’s what I’m seeing. When I hover or click on “Firefox” nothing happens.

rpm-ostree override remove firefox since it is included as image it takes always priority. This way you exclude/remove it and then can use flatpak or layer other on your choosing

Ok, this worked (though I needed to change get to set)
Now I am seeing a dropdown, with both of those browsers showing up. I wonder if this was happening because I’m using custom .desktop files for the other browsers. Maybe it had trouble picking them up?
Anyway, thanks for the help!

I have seen a similiar issue with setting up the default Mail app on Silverblue, see here. The fix was to tweak the ~/.config/mimeapps.list.
Do you have Categories and/or MimeType key=value pairs in the *.desktop file? If not, then that might be one of the reasons.
