Firefox and its bloody autocomplete

That's a problem I've never met on Firefox 2.x (maybe it existed before but I've never been in such a situation that it occures) To be precise, I'm currently on Firefox 3.0.4.

Have you ever noticed in the web sites you visit inputs that are automaticly completed by the couple login/password you've saved for this site but this form is not an authentication form? I do, many times... Developpers can test that. When firefox meet a textbox just followed by a password input, it thinks it's part of an authentication form. But it's not always the case. And it's not always excepted to be completed automaticly!

Well, it doesn't bother me too much for my own web sites ... the solution is to add the autocomplete="off" attribute to these baddy inputs:

<input type="text" name="nick" autocomplete="off" />
<input type="password" name="password" autocomplete="off" />

Et voilà! But when it's in the other sites, and autocompletion makes loose a form you've been filling carefully for many minutes, it could be disturbing...

I searched on the internet but didn't find anything about that ... The solution, if it's really disturbing for a particular site, would be to remove the couple login/password form the firefox data base for this site.

I understand it's not easy for the browser to figure out if a form is dedicated to authentication or not. Therefore I advice all developpers to think about preventing autocompletion for the inputs that are in the configuration before.
