Spell Check ALL Text Boxes in Mozilla Firefox

One of the many great features of Firefox is the built in spell checker. I write e-mails, publish articles, etc within the Firefox browser and this is a real time saver as I don’t need to copy my text into a spell checking enabled program to cover my back. The spell checker works in many fields in Firefox… but not all. In this guide we will learn how to enable the spell check in all fields.

Enable Spell Check for All Fields

1. In the address bar of Firefox, type about:config
2. Type layout.spellcheckDefault in the filter box
3. Change the value from 1 to 2

You are done, do a quick test by drafting a new e-mail, blog post etc and misspelling a word in the title field.
