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.
