Auto-saving, auto-filling passwords have made their way into most every browser, but, by default, they're only as secure as your ability to keep someone away from your keyboard. If your browser offers a master password option, use it—in Firefox, it's the only barrier between you and a single button unveiling all your passwords to snoopy friends or nefarious interlopers. Of course, if you're using the same weak password across all your site logins, you're just asking to have somebody get into your email, private social messages, and other private data. Using a secure password system can fix that. If you're using multiple browsers across different systems, you can keep your time-saving password fillers synced with Dropbox, or take care of bookmarks as well with the (Firefox only) Foxmarks.
