High HTML5 for Tor browser?
The Tor project has released version 6.0 of its anonymity-protecting browser.
The browser remains bundled within Firefox, and is now updated for Firefox 45-ESR, "which should mean a better support for HTML5 video on YouTube as well as a host of other improvements."
The widespread use of Tor by those accessing online child abuse material has lead to Mozilla involving itself in a criminal case in which an alleged Firefox vulnerability was used to unmask a Tor user. ®
