[Bug 2002904] Re: Firefox does not start in xubuntu 22.10: libgtk-3.so.0 not found

[Felipe Reyes]

I'm running Ubuntu 22.10, and getting the same problem:

$ /snap/bin/firefox
XPCOMGlueLoad error for file /snap/firefox/2277/usr/lib/firefox/libmozgtk.so:
libgtk-3.so.0: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

$ snap info firefox
name:      firefox
...
snap-id:      3wdHCAVyZEmYsCMFDE9qt92UV8rC8Wdk

installed:          109.0-2                 (2277) 250MB -

Switching to the candidate track fixed the issue for me:

$ sudo snap refresh --candidate firefox
firefox (candidate) 109.0.1-1 from Mozilla✓ refreshed
$ /snap/bin/firefox
Gtk-Message: 10:30:49.531: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it.
