The observant may recall recently I was looking for a password reminder app, only to be pointed out to that one already exists in Firefox (3.6.16) tools/options/security. However, those running FF might like to checkout FF add-on Unhide Passwords 126.96.36.199. A simple click in the password box that has a row of dots will reveal the password, another click outside the box will return to the dots. It doesn't work in those passwords/codes that start with an empty box (Bank etc.) or generally those not "remembered" by FF. This is of course not very secure if you are overlooked or other people have access to your PC(s) but if you are the sole user and have a bad memory it is quicker than the tools method above. Don't know if it works in FF4 as I'm not running that (yet)
Experience; is something you gain, just after you needed it most.
When faced with two choices, simply toss a coin. It works not because it settles the question for you. But because in that brief moment while the coin is in the air. You suddenly know what you are hoping for.
