Default Browser Setting Broken

[CalvinistNerd]

The window asking me to make Firefox my default browser always pops up, no matter what I select in the window itself.

It is not detecting that Firefox is the default browser. In the general section of the settings tab, when you click the "make default" button, all it does is reset the "always check" option back to normal.

Confirmed this is a flatpak issue, as I downloaded Firefox Dev straight from Mozilla and did not have that issue. It recognized firefox as the default browser and the window never popped up.

Running Fedora 28. Everything is up to date

Well that's most likely an upstream issue. Firefox can't get out of the sandbox flatpak provides. So there would need to be a portal (see https://github.com/flatpak/xdg-desktop-portal), which either allows firefox to set itself as the default browser or just opens the system settings default application section (like in modern android versions).

I just checked and I can definitely set firefox nightly (flatpak) as default browser in the system settings.

I have it set up as default in gnome-settings, but it's still asking every time I start it, even if I untick the checkbox "Check on every start"

I'm running Fedora 30 Silverblue Beta with gnome-shell-3.32.0-1.fc30.x86_64

I have the same issue. (FF Dev Edition, Fedora 33 Gnome Silverblue) If you uncheck the checkbox "Check on every start" when you get the prompt it doesn't persist.
However if you go into the settings and uncheck the setting there it does persist.

I wonder if the startup check not persisting if you uncheck it in the dialog is related to this issue or if it is an unrelated issue.
