Hi, Please Copy/Paste about:preferences#privacy to the Address Bar and Enter. The 1st Heading is Forms & Passwords. Go to Exceptions and put Google addresses in that you do not want saved. Please let us know if this solved your issue or if need further assistance. This works for Logins only. If wanting forms not filled in then it is all or nothing. Remove the Check Mark from under the Heading. Or find something that works for you here : https://addons.mozilla.org/firefox/search/?platform=windows&q=forms Please let us know if this solved your issue or if need further assistance.
