Lifesaver! BETTERTTV on P.M. Rated 5 out of 5 stars

If you have stubborn incompatible add ons you desperately want to use, this lovely tool will help you out with an alternative. BETTERTTV v7 users take note. If it can't quite install the normal way, get this, and install it with the userscript the old fashioned way. Just hit "userscript" on the NightDev page, instead of Firefox. Viola! Thank you deeply to the makers of greasemonkey

very good for script working and writing Rated 5 out of 5 stars

This is a good add-on that I will occasionally use to create my own scripts. It makes development easy and works well.
