Hey, thanks for trying the script out

This script broke on Chrome too. Apparently YouTube changed some of their internals. I'll update the code once I work on a fix

@xeraphim Apparently there were two issues. 1. YouTube updated their internals so I updated my script to accomodate that, and 2. the script had to run at document-start or else it wouldn't work :)
