Steps to reproduce:

Install flatpak from https://flathub.org/apps/details/org.mozilla.firefox

e.g. use https://www.bennish.net/web-notifications.html to trigger a notification

Actual results:

It shows in the top-right corner of the primary screen in an ugly rectangle box.

Expected results:

It should use the proper system integration for notifications. (in my case: GNOME)

(This already works when using Firefox outside of the flatpak.)

Technically, I guess this is a missing library (or patch?), i.e. libnotify, in Firefox. See https://github.com/flathub/org.mozilla.Firefox.BaseApp/issues/3 and https://github.com/flathub/org.mozilla.Firefox.BaseApp/pull/5 for how it may be fixed.

:c4609174, if you think that's a regression, then could you try to find a regression range in using for example mozregression?

No need to install a dependency, running Firefox after flatpak override --talk-name=org.freedesktop.Notifications org.mozilla.firefox made it work properly, the link you provided shows native notifications and not the top right version.

So, the configuration just needs --talk-name=org.freedesktop.Notifications to be added to finish-args

It's not really a regression, respectively no commit introduced it, you bot there.
It's just the packaging.

So yeah, then the permission is missing…
