Rated 5 out of 5 stars

Nice addon, haven't encountered any bugs yet. I have a few requests though. Can you add an option to autoselect video quality (maybe also player size, depending on quality)? I would also like to change icon to the official youtube one, it fits pretty well. I tried it with css but was unsuccessful, so an option would be nice.

This review is for a previous version of the add-on (2.4.1.1-signed). 

Hi, try using this CSS:

background: url(//youtube.com/favicon.ico) no-repeat;padding-left: 18px

It'll look this way: http://img689.imageshack.us/img689/9662/37327568.png

Also, version 2.5 includes HD playback support (not exactly what you wanted, but kind of)
