I use KeePass on multiple devices, all sync'd via SFTP to/from a database on a cheap VPS, and I'm really happy with my setup. KeePass lets me fill in the username and password fields, and I can configure the names of the fields if KeePass can't figure it out itself. My browser remembers not-so-secret stuff such as my address, and it's very rare I'd want additional form fields managed by KeePass, beyond username and password. That said, I wouldn't be surprised if there was a plugin that does that.
