I would think something like LastPass would be a good solution for you. Sure, it syncs across browsers and is stored remotely (on LastPass's servers), but at least it's encrypted and allows you to easily have very different passwords for every service you use.

Currently, someone just has to compromise your account on one third-party service in order to compromise every service you use (do you use Yahoo Messenger? I think all passwords are cleartext for that).

With LastPass, someone would have to compromise the (likely more secure LastPass service, or physically access your machine (and then compromise LastPass) in order to access your passwords. Seems just as easy to use, but more secure.
