Firefox Community Forum

Hi,

I am concerned that when I signed into my bank account today, the saved username which is autofilled by Firefox had been changed. The change was subtle -- from uppercase to lowercase letters -- but it wasn't me that changed it. This is a site I log in to often, almost every day.

Of course I am worried that this is some sort of hack.

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?
