 * Description:
 *      Extension for chromium and firefox
 *      Show password when double-clicking over password fields.
 *      Same as https://chrome.google.com/webstore/detail/showpassword/bbiclfnbhommljbjcoelobnnnibemabl
 *      but only whith double-click.
 *      I made a clone because when there is a non-personal automatic update, I don’t want my passwords stolen.
