3arabi is a Firefox extension that allows you to write text in Arabic language. Right click any text field and select "Write Arabic here" to write in Arabic using an English keyboard.
The add-on can transliterate your English letters (ex: akala el waladou el touffA7ah ) or translate English to Arabic using Google translate. (ex: The boy ate the apple).
This is useful in Google search, writing emails or writing comments in blogs when you have no access to an Arabic keyboard.
