Add English (United States) spell-checking support to Firefox with the **English United States Dictionary** add-on. It uses the actively maintained dictionary source from [Marco Pinto’s GitHub project](https://github.com/marcoagpinto/aoo-mozilla-en-dict).

This add-on provides an en-US dictionary for checking spelling while writing in Firefox. The previously distributed official Mozilla dictionary is now available through the separate [English US Dictionary add-on](https://addons.mozilla.org/en-US/firefox/addon/english-us-dictionary/).
