Edit Firefox's Dictionary

Firefox has a really nifty spell check feature, and I use the heck out of it. I recently found out how annoying it is that the “Add to dictionary” button is directly under the corrected words, causing me to accidentally add the misspelled word to the dictionary instead of correcting it.

To remove the misspelled word from the dictionary you will need to make you way to your profile directory and edit persdict.dat. It is, simply, a file with all of the words you have added to your dictionary.

Profile directory's can be found at these paths.
