Here's a trick I'd like to share with everybody. Lets say you tell your favorite browser Mozilla Firefox to remember passwords, because you can't possibly be bothered to remember your own passwords. Well, you take this handy dandy bookmarklet, stick it in your bookmarks menu, and when the time comes simply hit the bookmark, and out pops your password!
There are many more useful bookmarklets at this site as well.
oh no, that's a horrible security vulnerability! you mean password box text is available in the DOM tree? :(
