Disable save password in Firefox by Group Policy

active-directoryfirefoxgroup-policy

Alright, so a huge security flaw is that Firefox saves passwords in plain text.
How can we disallow saving of passwords in Firefox the quickest way.

Is it possible by Group Policy or anything like that?

Of course a trouble will be that the user easily can change browser.

But would be nice to not allow it for Firefox at least.

Firefox has no native GPO support. You can use a mozilla.cfg file that you push out with Group Policy File Preferences that contains lockPref("signon.rememberSignons",false); in it. This will disable the password remember features. You'll also have to push out a few other changes to make Firefox load the mozilla.cfg file. It's all detailed in that link.

Alternatively, Frontmotion makes a pay-for version of Firefox that has GPO support. The problem is that it uses a different icon since it's not a vanilla Firefox distro. This confuses most end users.
