A couple of weeks back I posted a blog entry about caching all youtube videos on to your squid proxy server. This is working great, but now youtube lacks the ability to loop your video again and again and again... unless! you add the same video a million times in your quick playlist.
Nevermind, Greasemonkey script to rescue! You need to make sure you have greasemonkey installed. If you do you will have a little monkey icon (bottom right corner).
Greasemonkey can be installed from https://addons.mozilla.org/en-US/firefox/addon/748
Once you have greasemonkey you will need to restart firefox. The thing I like about installing greasemonkey scripts is that I don't have to restart my firefox :D
Now you can install Loopy for YouTube. Once installed, go back to your youtube video and hit refresh.
You will see a little [Loop] text under the video. ![]()
This apparently has some issue with other firefox extensions but I didn't notice any. The loop feature works perfectly even when under full screen!
