Firefox spell check

Carrying on from previous post.  I have been Firefox spell check since Firefox 2.0 and have just managed to added a miss spelled word into the dictionary.

Quick Google search and I have found out how to edit the entry that was added.  This is only for windows, no idea how to do it for mac or Linux.

1. Open C:\Documents and Settings\%username%\Application Data\Mozilla\Firefox\Profiles or click run and type %appdata%\Mozilla\Firefox\Profiles.
2. Open your profile folder, it should have a .default extension.
3. open persdict.data with notepad or any other text editor.  Delete or add words and save.

Had to write this down as I am getting old and tend to forget things these days unless they are documented.
