$update-alternatives --list x-www-browser
/opt/firefox/firefox
/usr/bin/google-chrome
/usr/bin/iceweasel
$sudo update-alternatives --config x-www-browser
There are 3 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/google-chrome 200 auto mode
1 /opt/firefox/firefox 70 manual mode
2 /usr/bin/google-chrome 200 manual mode
3 /usr/bin/iceweasel 70 manual mode
Press enter to keep the current choice[*], or type selection number: 2
Then in Cinnamon I go to the option but the menu only show Firefox.

In XFCE i put google-chrome in preferred application but continus asking for it?
