Edit Firefox’s Spelling Dictionary
If you have used Firefox’s built in dictionary, you will know there is a limitation to it. Firefox allows you to easily add words to dictionary, but lacks a user interface for removing words. This can be a problem since the “Add to dictionary” button is directly under the corrected words, providing easy access for adding misspelled words to the dictionary.
Since I frequently add misspelled words, I had to learn the method for removing these words. To remove misspelled words, first close down Firefox then navigate to your profile folder. The folder’s location varies 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 in your profile folder, look for a file named persdict.dat, and open it with your favorite text editor. Inside you’ll find all of your custom defined words, each on their own line. Just delete the words which don’t belong and save. Firefox will no longer incorrectly identify those misspelled words as correct.

From the always useful Lifehacker:
- Open your application data folder. On XP or Vista, go to your Start menu and hit Run (or just press Windows-R) and paste in %APPDATA%\Mozilla\Firefox\Profiles; on your Mac, navigate to ~/Library/Application Support/Firefox/Profiles.
- Find your profile folder, which by default should look something like xxxxxxxx.default.
- Inside your profile folder, find the file called persdict.dat and open it up in your text editor of choice.
- Now just find the misspelling, delete it, and you're done.
This still works in Firefox version 44.0.2 (2016-02-12) - though the profile folder does not necessarily end in ".default"; a sample name is "yynxpuma.default-1439568940109". – Peter Mortensen – 2016-02-13T18:28:33.313

See "Firefox Dictionary & Spell Checker Hacks: Edit Misspelled Words, Merge with Word Dictionary". Basically, you need to manually edit the file named persdict.dat.
