Doens't work with Firefox 17.16...etc Rated 3 out of 5 stars

it's a great Addon-on, and the best part is the 3 buttons all together, but since it doesn't work neither with 16, nor 17, so I'm going back to Firefox 14, in case you make it compatible with the 17, just let me know.

I think I've figured it out now and it shoud work with latest Firefox versions.
