Firefox Spell Checking - Add Word / Remove Words / Edit Words31 Jul 2007
Question: I just accidentally added a misspelled word to Firefox’s built in dictionary – how do I remove it?
This is a good question! Thankfully, someone at Mozilla decided the user dictionary should be stored in plain text and newline delimited. A big thank you from Chris on this one!
The only challenge is locating your Profile and then your personal / user dictionary file. The personal dictionary is called persdict.dat and lives in your Firefox Profile folder.
The Firefox Profile Folder is located in different places depending on what Operating System you are using:
- Windows XP:
C:\Documents and Settings\%USERNAME%\Application Data\Mozilla\Firefox\Profiles\????????.default\
- Windows Vista:</br/>C:\Users\%USERNAME%\AppData\Roaming\Mozilla\Firefox\Profiles\????????.default\
- Mac OS X:
Once you have found your profile folder you need to edit the persdict.dat file. Using your favorite text editor open up that file and edit out / add in the words you desire.
You will need to restart Firefox before it will see any words you updated.[
