signon.rememberpassword

how to make signon.rememberpassword false in firefox with javascript (not manuallay).
my goal is to disable remember password feature in firefox when user login into my site and then enable
it again when user log out from my site.

sorry it was signon.remembersignons

I don't think you can, for security reasons.

I may be wrong, but it may indeed be possible. You see, there is a certain file called prefs.js :

you could utilise some of the methods this file exposes with your script to toggle between this, here's more info :

Playing around with these type of settings, is always a hot topic which may end up in a heated debate as to why / why not do this type of thing ;)

i hope my post was useful :)

thanks hans

I suppose AJAX could be used to alter the config, though script execution confirmation and a browser restart wold be needed to make it all work.

Also to avoid autosave feature you could use Flash-based login form.

P.S.
- FF asks if it should save some login and password. You say NO. Then to log in again some other day you by mistake enter something wrong on the same page and FF asks again if it should save it or not, while if you type it correctly it stays quite. Resume: The da.mn bas.tard saves it all after all! =S
