How to Remove Misspelled Words in Firefox for Windows

Edited by Teresa, Chris, Eric, Flickety and 5 others

While there are probably a few ways to edit your 'accidental corrections' in Firefox, this way edits your persdict.dat file. This article focuses on Firefox 9.01 and Windows 7.

EditSteps

1
Locate your persdict.dat file. The easiest way to do this is as follows:
- Open a folder onto your desktop.
- In the upper right hand corner of the folder, type in 'persdict.dat' in the search box. It will, by default, look in the Libraries folder, and needless to say, won't find it.
- Underneath the words, 'Search again in:', click on Computer so that it will look through all of your computer.

Another, quicker way:
- Click on Help in Firefox (it may be under the orange button).
- Click on Troubleshooting Information. A page will open with info about your Firefox installation.
- In the middle of the first section (Application Basics) is Profile Directory, with a button to Open Containing Folder. Click it.
- persdict.dat should be in the folder that opens - scroll down or search for it.
3
Once it has been found, open it. Your computer may not know what to open it with. Select the WordPad (or Notepad) program to edit it with.
4
In WordPad, start going through your list of words. Look closely. Some of the words will be pretty easy to miss. Here are three misspellings that have been found.
- Don't be surprised to see some odd characters in the file. Those are accents and such that are added to words, such as in the circled word in the list screenshot above (with this screenshot showing how it appears when published).
5
Select and delete the misspelled words. Look over it a couple of times, or better yet, have someone else look it over.
6
Save your file. Press CTRL S (or click on the floppy in the upper left corner) to save.
7
Restart FireFox. The misspelled words should now have been removed.
