Tor Browser crashes at startup - firefox 47.0 to blame??

Tor Browser was working great everyday, until I updated today to 6.0.1

The newest updates says it updates firefox to 45.+ but mine is already at 47.0. Is there a mismatch between versions that is now causing the startup crash?

Would love to provide logs/more info. if I could find them.

The only logs in /users/local/tmp are huge firefox.exe crash dumps. No actual usable text in them, just scrambled junk.
