First, you put your e-mail address in a public forum. I removed it, but please be a bit more careful with your email address :) Second, why are you worried about the Firefox profile? You can easily encrypt your passwords using a Master Password [[How to set up a master password]]. If someone has physical access to your computer (which is what would be required to view your Firefox profile) they can also install malware, keyloggers, etc. It's best to use full disk encryption on your computer to protect all your files from physical access, and then ensure you keep your OS and Firefox up to date to protect against security holes.
