Firefox (4) allows me to
Accept cookies from sites (with
Exceptions to Allow or Deny for some). However, as far as I can see, it ain't possible to use the option
Keep until: I close Firefox and still keep some cookies when I close.
Is it somehow possible to keep only a whitelist of cookies and clear all the rest on close?
Does this even make sense, or should I just make a whitelist of cookies and keep those regardless of closing Firefox?
