Its called sextortion.. and that exact same email has been floating around.
And no.. they have nothing on you..

All they have is a password from a website they hacked and if you happen to have that password across all sites,we'll you're really in a bad place..

Don't worry, the browser thing is a complete lie.

Change your passwords and ignore those hackers.. I wouldn't try and play with them.. they have a valid password, so don't get stupid and piss them off.. Just saying.
