The Firefox logo should be replaced by the Tor Browser logo.
The large word Firefox should be replaced with TorBrowser.
The text is wrong. Perhaps 'The TorBrowser is designed by The Tor
Project, based upon the Firefox browser, to keep you in control of your
privacy and anonymity online.'
The 'Privacy Policy' text and link needs to be removed.
The light grey text at the bottom about the Mozilla/Firefox trademarks
should be replaced with '"Tor" and the "Onion Logo" are registered
trademarks of The Tor Project, Inc.'
