Torbutton's readme still talks about toggling

https://gitweb.torproject.org/torbutton.git/tree/README has the very first FAQ entry of "I can't click on links or hit reload after I toggle Tor! Why?"

and at the very end it says

   There is currently one known unfixed security issue with Torbutton: it is
   possible to unmask the javascript hooks that wrap the Date object to
   conceal your timezone in Firefox 2, and the timezone masking code does not
   work at all on Firefox 3.

and I bet a lot of the stuff in the middle is obsolete now too.
