Jean posed an interesting question yesterday - how exactly does one edit their personal spellcheck dictionary in Firefox, particularly if you’ve accidentally added a couple of badly spelled words? It’s a question I’ve wondered about myself but hadn’t had the motivation to look into until now. It took me a few minutes to find the answer, but it’s actually really easy.

Find your profile folder in your Firefox directory (mine’s under FirefoxPortable\Data\profile) and locate the file called persdict.dat. This file contains all the words you’ve added to your approved spellcheck list for Firefox. Just open the file in your favorite spreadsheet program and delete the rows containing words incorrectly added to the dictionary, save the file again, and close it. Simple as that!

You can also find a few other ways to modify your dictionary here.
