Don't enable or install browser plugins
The Tor Browser will block browser plugins such as Flash, RealPlayer,
Quicktime, and others: they can be manipulated into revealing your IP
address. Similarly, we do not recommend installing additional addons or
plugins into the Tor Browser, as these may bypass Tor or otherwise harm your
anonymity and privacy.
