Comment (by zyan):

 (yan here)

 I am fairly certain that the 301-redirect cache timing attack mentioned at
 the end is not feasible thanks to #1517, at least.

 Note there is an chrome bug for a non-timing HSTS attack that has the same
 fingerprinting impact as Sniffly. I believe it works in Firefox as well.

 Chrome fixed it and then reverted the fix because it broke things. TBB
 should probably just copy their original fix.
