I cannot get firefox to delete all of my browsing history, specifically form and autocomplete information. Tried going through the steps multiple times.

I have tried to clear all of my data history in firefox because some very sensitive information from filling out college forms and whatnot has been saved and is being used in autocomplete. Because of a bad wireless company, our network has to be "unsecured" to work, and I do not want anyone getting a hold of extremely important personal information. I have gone into settings and tried clearing the cache, using private browsing, deleting all past history, etc... but firefox won't delete any of my history, even browsing. Please help! Thank you.

Rename or delete formhistory.sqlite (plus formhistory.sqlite-journal and formhistory.sqlite.corrupt and formhistory.dat, if they exist) in the Profile Folder in case there is a problem with the file that stores the "Saved Form" data.

This will remove all saved form data, so you may want to rename formhistory.sqlite to formhistory.sqlite.sav or move the file to another folder in case you need to recover some saved data.
