First of all, thank you for this awesome script :) I've been using it for quite a while and it really made YouTube a lot nicer.
However, lately I've been getting some errors from HQTube. Some YouTube pages don't have a related videos section anymore, for example. Also, YouTube now has HD-quality videos and this script can only use the HQ-video's or anything in lower quality right now.
I've been getting a different error: HQTube says it needs to be updated, but plays the video fine: <http://www.youtube.com/watch?v=TftFnot5uXw>
First of all, thank you for an amazing work you have done. Youtube is running smooth after adding your script. But I've noticed that movies placed on youtube shown on different sites like failblog.org are still played by gnash. I've tried adding http://*youtube.*/v/* to pages but it doesn't work. Any suggestions?
