I need an extension or add-on for the Ubuntu web browser (the browser which is provided by Ubuntu other than Firefox) to block some websites in my Ubuntu 14.04.
I need an add-on like the 'Leech Block' add-on for Firefox. The greatest advantage of that add-on is that we can block websites on scheduled time intervals. This is the most important feature I want.
So can anyone suggest an add-on of such type for Ubuntu Web Browser?
