Ever since switching to Firefox 3.6 (now 3.6.3) & latest Vidalia bundle w/ Polipo, can
not connect - always get "The proxy server is refusing connections Firefox is configured to use a proxy server that is refusing connections." Checked proxy addreses / ports - they're default for Torbutton. Uninstalled / reinstalled several times - no joy. If I disable torbutton, FX works fine (even w/ Tor & Polipo still running).
Never had this prob when vidalia bundle still used Privoxy & before FX 3.6. I did get current bundle to work once or twice by uninstalling, but after reboots, wouldn't work.
