"new identity" (& "cookie protection") is always gray
when i first installed tor(button) it worked just fine, now (for a couple of weeks actually) the "new identity" option in the browser button is always gray and cant be selected. i tried de- & reinstalling both vidalia/torbutton and firefox but it doesnt fix it. why is it doing that and how can i fix it?
ps: its just torbutton that wont do it, vidalia can still switch identities.
