In this article I will show you how to change the default Internet Browser in Debian, Ubuntu, Linux Mint and other Debian based Linux distributions.
I will change the default internet browser from Firefox to Konqueror.
If you don’t have the Konqueror browser installed already, install it with:
$ sudo apt-get install konqueror
Now, let’s set konqueror as the default internet browser, with update-alternatives –config x-www-browser, used as root.
$ sudo update-alternatives --config x-www-browser
There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/firefox 40 auto mode
1 /usr/bin/firefox 40 manual mode
2 /usr/bin/konqueror 30 manual mode
Press enter to keep the current choice[*], or type selection number:2
Hit the number representating the browser you want as default and press Enter, to apply the changes.
