Edit Firefox Custom Dictionary

Today I clicked to add a word to my Firefox dictionary by accident. After searching around everywhere in the Firefox menus, I couldn't find anywhere to edit the dictionary. Turns out you can't. So, browse to the following locations depending on your operating system:

Windows XP

C:\Documents and Settings\[User Name]\Application Data\Mozilla\Firefox\Profiles\xxxxxxxx.default\

Windows Vista

C:\users\[User Name]\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default\

Mac OS X

~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/

Linux

~/.mozilla/firefox/xxxxxxxx.default/

Once you are in the correct location for your operating system, look for persdict.dat, and open it with your favorite text editor. In this file, you will see line-by-line all of the words you have manually added to the dictionary. Simply delete the entries you don't want.
