(Firefox Add-on): Just like torrent files, YouTube videos can get pretty nasty too. Judging from the quality of comments left by the YouTube community, you shouldn’t be surprised to spot some nothing-better-to-do YouTubers uploading fake videos with misleading titles (say, a video full of emoticons titled Pink Panther 2 Trailer: watch).

With TabCloser, you can close all tabs of a specific domain in just 2 clicks. After installing the Firefox add-on, there will be a ““Close all example.com tabs” option when you right-click on a tab.
