What's the difference between x-www-browser and gnome-www-browser?
Solution 1:
Both are scripts that, when configured by update-alternatives, call the default application for internet browsing on a GUI environment.
The script x-www-browser calls the application configured to run on any desktop environment that runs under X Server, while gnome-www-browser application configured specifically calls for GNOME. Similarly, www-browser is a script to call the default browser on a TUI (text-based user interface) environment, such as w3m or elinks, for example.

You can check which browser they are associated with the commands
update-alternatives --display x-www-browser update-alternatives --display gnome-www-browser -
To list all the alternatives to these scripts, use
update-alternatives --list x-www-browser update-alternatives --list gnome-www-browser -
To configure a default browser, use the commands
sudo update-alternatives --config x-www-browser sudo update-alternatives --config gnome-www-browser
Since these scripts can call different browsers, it may happen that a certain program call a browser other than the default browser. This often causes confusion for some users, but this issue can be fixed by running the command sudo update-alternatives --config as explained in item 3, above.
