it is time to start to concerrn about your knowledge on firefox password scheme. Firefox does not store user passwords on its servers rather it stores on users’ computers.

Right? Yes;-)

Maybe one should consider putting so much trust in mozilla.org’s servers, and more than that trust all these firefox addons. This article just skims the surface on how easy it is to obfuscate malicious code in jar files, and firefox addons in general. So now lets involve something as important as passwords with this so very secure trusted third party, and also mozilla.org’s server storing all these addons. I mean nobody would attack something as unpopular as mozilla.org, right? Not.

If you are looking for a good way to generate a unique, random password (alphanumeric, hex, or all printable characters), GRC is by far the easiest way to go, just open, cut, and paste. Plus, you also eliminate the possibility of a keylogger ever capturing your password (as long as you continue to only cut and paste it).

I also use foxmarks to keep my boxes’ passwords (safely, i hope) synchronized, as well as my bookmarks. I’ll give some of these recommendations a try, tough.
