Change sensible-browser
Some of my apps use the script sensible-browser to open web pages. This script opens /etc/alternatives/gnome-www-browser or /etc/alternatives/x-www-browser. On my machine, these two are symbolic links to Google Chrome (which I rarely use). I want to use Firefox instead, so I made them into symbolic links to firefox.
Now if I use sensible-browser, Firefox is used. However, for some inexplicable reason the symbolic links are regularly reverted back to point to Google Chrome!
What is the correct way to change sensible-browser?
If you want to change gnome-www-browser to point to say /usr/bin/firefox
You can do
sudo update-alternatives --set gnome-www-browser /usr/bin/firefox
Similarly you can do the same to the other one also i think.
Edit:
Or..
You can do
sudo update-alternatives --config gnome-www-browser
which gives a list of all the browsers to choose from, from which you can select one of them.
If you’re using snap managed firefox using update-alternatives won’t work, but you can open firefox and go to it’s settings (about:preferences) and click "Set default" button.
