CookieSwap от ExtUp

CookieSwap is a Firefox web browser extension. If you have multiple logins for web based accounts (like Gmail, Yahoo! mail, Facebook, etc), then CookieSwap allows you to easily switch between those different accounts by creating multiple "profiles" that can be easily changed which will 'swap' the 'cookies' that the sites use to know you.

Additional features of CookieSwap:
- cookies manager that allow to view, add, edit and delete cookies.
- export of cookies in "standard" (Netscape) format.
