command line select preferred browser

debian 10

mate -> control center ->
preferred applications -> internet -> web browser

Some times pale moon is on the list. Sometimes not. Even
if pale moon is present and you select pale moon and set pale moon as the
default browser in pale moon's settings, then it does not work.

I found these commands
sudo update-alternatives --install /usr/bin/x-www-browser x-www-browser /usr/bin/palemoon 100
sudo update-alternatives --config x-www-browser

I have not tested the first command because I cannot understand it. There
is no /usr/bin/palemoon 100 file. Why is it palemoon 100?
Thanks.

man update-alternatives gives a decent rundown on its function. 100 is a priority rating.
To find where palemoon binary exists on your system:

Code: Select all

which palemoon

Use galternatives to add new alternatives, the command line invocation can break your system if you get it wrong.

And edit ~/.config/mimeapps.list as well.

There is also ~/.config/xfce4/helpers.rc for the Xfce desktop, use the exo-preferred-applications utility to change that.
