Firefox 2.0+, by default, spell checks only multi-line text areas. To spell check single line text fields such as search boxes you typically have to right click and click "spell check this field" in the context menu. The following tweak will make it so that spell check is always on by default for ALL text fields.



1. Open a new tab and type about:config in the address bar and press Enter.
