Normally form manager fills form with data, it have stored. It is great for auto-filling login/password input fields, but sometimes it can cause problems. For example when i edit my bug reports on http://bugs.php.net Mozilla prefill form fields with data, came from my first bug report, i have submitted, while i need to preserve these fields with information, they're filled by default (for example bug summary or version of PHP). So form manager needs an ability to cancel its automatic form filling and revert all form fields to their default values.

I'm confused. Are you talking about form manager or password manager. Form manager does NOT do any automatic form-filling. Could you please give a step-by-step sequence starting from a fresh profile that demonstrates the problem. That would clarify any confusion.

No reply from reporter in over a month. So I'm going to make some guesses here and assume that reporter meant password manager rather than form manager. If so, it appears as though he is talking about bug 153986 *** This bug has been marked as a duplicate of 153986 ***
