Autofill / remembed values

Basically Firefox keeps remembering what i put in forms; which is great in some situations, except If i want to make a post or reply on an imageboard and i have to delete my username and my subject every single time, as firefox has remembered values i inputed when i first posted.

I have tried putting in different values, such as alt+0168, but it always reverts back to what it assumes should be the default value.

Thanks in advance for any help.

Op here; this may be because i have the google toolbar installed; i'll uninstall it and see what happens.

Tools > options > privacy >

uncheck "save data inputted into forms"

go back to said image board delete what you put in name / subject and press the down key so it highlights what you've put in it, then press shift + delete.

FIXD.

Uh, some boards seem to save your form data in cookies. Block cookies and see if that helps.
