Not a big problem with Firefox, but if you forget the password you used to access a web page or site in IE, it can be a right pain to retrieve it.
Found this little script that runs as a bookmark: Reveal Password
Simply right click on the link above and add it to your bookmarks – sorry, favourites.
Next time you come up against a site you have the password “dotted” out, simply go to your favourites and choose this link. A small popup will appear showing the password in plain text.
This also works for Firefox, and is the lazy mans way of discovering the password.
