Many people use Firefox these days because of the great spell checker. However, sometimes spellcheckers get filled with entries which we don't wish were there. Here is lifehacker's manual take on how to fix the problem:
http://lifehacker.co...r-firefox-dictionary.
Instead why not create a web service or a Firefox add-in which first locates the persdict.dat file and then displays it in the browser. Next using a different dictionary, it highlights possible misspellings in the custom spellchecker dictionary. It could be called "Firefox Spellchecker Tuneup"... of "Firefox Spellchecker Spellchecker" :-).
I suppose as a bonus the web service/application/Firefox add-in could offer to also tune up the MS Office custom dictionary, which apparently is located for Vista and Office 2007 at: C:\Users\[user
name]\AppData\Roaming\Microsoft\UProof\CUSTOM.DIC and is just a list of words separated by carriage returns just like the Firefox one.
