Mozilla won't work???? What's wrong with your system. Did I make the mistake of downloading the Mozilla 6.0 does it have problems?? HELP!!!!!!!!!!!!!! I'm thinking Roadrunner Turbo is to fast for Mozilla Firefox 6.0 because my Problem with Mozilla didn't start until the Roadrunner Turbo was installed last week?!?!

You already told me to do this on your last answer it didn't work. So, what will work now to get Mozilla Firefox to operate without a 414 error and 404 error. E-mail doesn't still work???? I think it's still by stupid Roadrunner Turbo box getting new one Saturday see if that doesn't do the trick in fixing on my Software issues with Mozilla Firefox 6.0???

If clearing the cookies doesn't help then it is possible that the file cookies.sqlite that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete cookies.sqlite-journal and cookies.txt, if they exist, in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.
