I love it! Rated 5 out of 5 stars

This is THE add-on for people who are slow in Arabic typing (like myself), and for people who do not have Arabic keyboards.
I fell in love with it the minute I installed it, it lets you update your Twitter or Facebook status, and you can write an entire book in Arabic with Yamli notepad!
It's by far the most useful add-on for Arabic users.

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