GREAT!!! Rated 5 out of 5 stars

Man this add-on is a SAVIOR. It's slick, I've been using it for 2 days now and it seems great, no problems.
Pros:Faster Arabic writing, you don't have to use a toolbar(like other apps)
Cons:in settings the "Buttons" option is still under construction.
Overall this is definitely an add-on that any Arab can't live without HEHEHE.

This review is for a previous version of the add-on (0.9.4).
