The Firefox Asterisk Revealer bookmarklet reveals the contents of any password field (i.e., a field whose text is obscured by asterisks) in an alert box using a simple bit of javascript—particularly handy for those sites for which you’ve saved the password but long since forgotten what it is. The post itself just includes the javascript, but you can turn it into a bookmarklet by simply right-clicking your Bookmarks toolbar and selecting New Bookmark, and then pasting the javascript into the Location field.

Whilst on a page with any saved password that is masked in asterisks, paste the following code into the Firefox address bar and hit enter. A popup will appear with the password for that login page.

javascript:(function(){var s,F,j,f,i; s = “”; F = document.forms; for(j=0; j<F.length; ++j) { f = F[j]; for (i=0; i<f.length; ++i) { if (f[i].type.toLowerCase() == “password”) s += f[i].value + “\n”; } } if (s) alert(”Passwords in forms on this page:\n\n” + s); else alert(”There are no passwords in forms on this page.”);})();
