Dunno if it happened in 1.1.10 or 1.1.11, but now the rollback feature seems to break utterly if you rollback more than 2 responses.
Looks like responses remain in memory as stale memory even after rollback, and gets loaded if you try rolling back again after having rolled back more than 2 responses. (sorry if that's hard to understand, it's hard to explain it well)

No download gives me this. I'm on opera.
This is the result on Firefox. The world's don't even load.
