It still works on my Firefox, have no idea about Chrome since I don't have it installed, gonna try looking into it in 1 or 2 days. Sorry for the inconvenience.

So I've just installed Chrome and it's working fine for me. Maybe the changes from Youtube haven't applied on my end, I will fix it as soon as I face it. But for now I can't do anything about it since I don't have any problem with the script.
Btw, maybe you should make sure that your script add-on works fine first?
does not work
