Rated 4 out of 5 stars
I contacted support already, but I should post this anyway. There is a bug in version 2.2 that makes Firefox shut down when it visit some pages, like http://dpaste.com .
Despite of this, I give the add-on 4 stars. I just have it disabled and I enable it when I'm going to use it. It's a very useful extension and I hope it gets fixed soon.
