[Lubuntu] Change default browser

Open terminal (Alt+Shift+T) and paste the following line:

sudo update-alternatives --config x-www-browser

Then it should prompts for your input:

There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).

  Selection    Path                           Priority   Status
------------------------------------------------------------
  0            /usr/bin/google-chrome-stable   200       auto mode
  1            /usr/bin/firefox                40        manual mode
* 2            /usr/bin/google-chrome-stable   200       manual mode

Press enter to keep the current choice[*], or type selection number: 

I want to keep it as firefox, so I would enter 1 in my case. The next it starts up, firefox would be my default browser instead of chrome 🙂
