[tor-talk] Making TBB undetectable!

[aka]

Wasn't Mozilla working on a Firefox which uses Tor for "Private Browsing"?
https://wiki.mozilla.org/Privacy/Roadmap/Tor
If millions of people would use the same Firefox on the same version
with mostly the same browser/javascript behaviour, it would make TBB
obsolete. Wouldn't it make more sense to include those anonymity patches
into the mainline Firefox and make them opt-in if the user uses Private
Browsing?
