CookiePie

sign on with two users in one place without having the cookies from one tab stop you from being new one. To activate it open the browser context menu (right mouse click) on one of your open tabs and select 'Toggle On / Off CookiePie'. In practice it is very useful if you are used to working with multiple accounts or used more than one profile on a website and want to connect with both. The fact is that with CookiePie the days of those old and annoying limitations are numbered.
