Comment(by mikeperry):

 Replying to [comment:11 t55wang]:
 > I've implemented preliminary versions of both. Right now, the "tiny
 change to FF" approach works except for the SSL handshake, which is to say
 it does not work. The "modifying OP" approach works, but doesn't deal with
 some errors very well yet. I will keep you updated when either or both
 approaches do in fact work.

 How exactly does the SSL handshake fail, and in what cases?

 And for the OP case, what does "not dealing with some errors very well"
 mean in practice? The user experience for errors is already pretty bad. I
 think in practice we can ignore most UX issues with the errors since the
 perf benefit for the good case is so clear.

 Also, can you attach patches as well? It will make it easier for us to
 make suggestions/decisions.
