How can I block every website except for one; twitter.com with firefox?
I want to create a twitter fountain on a congress, I am organizing. I do not want the participants to allow anything else but to twitter with their friends. Is there any possibility to realize this censorship for the participants?
I am looking forward to your answer!
With kind regards,

Sure thing, use the Glubble extension for that.
