This question already has an answer here:

I have set Seamonkey as default browser within Seamonkey and under preferred applications.

Yet apps that have a help section always use Firefox to go to their help website.

Any way to stop that?

$ sudo update-alternatives --config x-www-browser
There is only one alternative in link group `x-www-browser`
(providing `/usr/bin/x-www-browser`): `/usr/bin/firefox`.
Nothing to configure. 
  • Ubuntu-Mate 16.04 LTS Xenial
  • Mate Desktop

Update in response to request:

update-alternatives --get-selections | grep -i browser
gnome-www-browser auto /usr/bin/firefox  infobrowser auto
/usr/bin/info  x-www-browser auto /usr/bin/firefox

How did you install Seamonkey? – Zanna Jan 29 '18 at 21:21


I kept plugging away and trying different things.

I found a fix.

I used this

gksu synaptic-pkexec

instead of


Now when I click on Visit homepage within synaptic, it uses Seamonkey instead of Firefox.
