YouTube definitely is an awesome site with good usability and stuff. One thing that i really miss(ed) was a simple "auto replay button". I for once got really needy of such a feature and even tweeted about it. One of my friend in twitter asked me to try writing an add-on for the same and here it is.
Why is such a feature even needed?
Some like me, when stumbled upon an awesome song(like Handlebars by Flobots or Viva la Vida by Coldplay), would really want to hear it more than once. And in YouTube without an Auto replay button, its really a pain.
Install your copy from here. As always, report any bugs/issues here. Feature requests are always welcome!
ps: You don't need a mozilla account anymore to install the experimental add-ons. You just need to check the "Let me install this experimental add-on" checkbox and carry on with your installation.
Update 0.0.4: Added options to choose the portion of the video to be auto replayed. [Recommended install]
