Setting the desktop file name in the special application settings to `firefox` like this fixes the issue, but that's just a workaround:

Other distros don't have this issue. Also noticed that "Window class (application)" appears as "firefox Firefox", which I think should be just "firefox". Which is probably caused by https://github.com/void-linux/void-packages/blob/1129a5bdb274aa93d2b8a6dcf9513cd49b9c22b7/srcpkgs/firefox/template#L216 and https://github.com/void-linux/void-packages/blob/1129a5bdb274aa93d2b8a6dcf9513cd49b9c22b7/srcpkgs/firefox/patches/fix-firefox-desktop.patch#L13

Edit: I am going to build firefox locally with `MOZ_APP_REMOTINGNAME="firefox"`, and report back.
