Enable/Disable Form Fill Button

I think you need to give the user more control over the automated Form Fill feature. At first I thought it would be a great feature, and save me time in typing my postal address. But whatever time it saves me from typing my postal address on one site, I then loose on deleting information it has incorrectly entered on another form on another site. And now it seems to be that I spend more time deleting information in a form such as when entering a post on a forum, posting to my blog, answering a questionnaire, that now it the feature just doesn't seem worthwhile.

There needs to be a button for the extension that could sit in the status bar in Firefox that I could click on or off to quickly enable or disable form fill. At the moment it is just entering data randomly into too many forms, just because it might have the word address in the form field label. But address could mean many things, and typically I want to enter an URL and instead the first line of my postal address is inserted. It is getting frustrating now.

I requested something similar 9 months ago http://getsatisfaction.com/vidoop/topics/feedback_manually_add_ignore_sites and still nothing has improved.
