How to Edit the dictionary? Thunderbird 2.0.0.23

Hello,
I want to remove a word from the Thunderbird dictionary. I use 2.0.0.23.
I cannot find this.
Thank you

With Thunderbird closed, navigate to the Profile Folder and locate the file persdict.dat. Open that file with a text editor (Notepad, for example) and remove the word then save the file to the same location and same name.
