My OS is Debian stretch (mate Desktop) Since about 2 years I have a problem with default setting for application browser(in mate-control-center) and firefox. whenever I let firefox set itselfs as default browser in (about:preferences) my prefered application settings in mate-control-center changed from firefox-esr to thunderbird for default browser. And the other way around.
Both seemed somehow registert
alex@Taomon:~$ gvfs-mime --query x-scheme-handler/http
Default application for 'x-scheme-handler/http': firefox-esr.desktop
Registered applications:
thunderbird.desktop
firefox-esr.desktop
Recommended applications:
thunderbird.desktop
firefox-esr.desktop
alex@Taomon:~$
alex@Taomon:~$ gio mime x-scheme-handler/https
Default application for 'x-scheme-handler/https': firefox-esr.desktop
Registered applications:
thunderbird.desktop
firefox-esr.desktop
Recommended applications:
thunderbird.desktop
firefox-esr.desktop
alex@Taomon:~$
How can I remove thunderbird as registered application for x-scheme-handler/http
and x-scheme-handler/http
s. I hope then my Error will be gone for good.
edit
In ubuntu (focal) is only firefox registert.
alex@Guilmon:~$ gio mime x-scheme-handler/http
Default application for “x-scheme-handler/http”: firefox.desktop
Registered applications:
