In case you haven’t downloaded version 3 of Firefox, here is one good reason – password remembering. In the old FF it would wait for the user name and password submission to be posted before asking if you wanted to remember the user name/password. That sucked because if you screwed it up then you have a user name/password that would stick there until removed or changed.
Version 3.0.1 is my latest Firefox. When I submit a user name and password to a site it goes ahead and processes it but pops an info bar in the top of the browser asking if I want to remember the password, not now or never for this site. It’s just great that it does it after I’ve submitted. Some times I forget my password and it’s good to see it go through successfully before telling Firefox I want to remember it.
