I would like to know how passwords r cracked bcoz of using lower version browsers... or browsers wit less features..? Do the hackers some special softwares for doing these things..?

Why do you want to know?

My id was traced by someone... now I could not use it anymore... just like to know how thing work...

There are a whole bunch of ways a password can be stolen from a user. Most of them have nothing to do with actually hacking the password. Keystroke recorders, social engineering, pure guesswork and others.

k.. thnx
