Change the default web browser
After I read about the new terms of use for Firefox (see links at the bottom), I wanted to give LibreWolf a try.
Installation
On Ubuntu I added the external Debian repository:
On Void Linux I added an extra repository from GitHub:
Set as default browser
I used xdg-settings to define LibreWolf as my default web browser:
xdg-settings set default-web-browser librewolf.desktop
On my Void Linux machine I had to install the package xdg-utils first because the xdg-settings command was missing:
sudo xbps-install -Su xdg-utils
To ensure that librewolf.desktop exists you can take a look into the directory `/usr/share/application`.
