All,
I just landed https://bugzilla.mozilla.org/show_bug.cgi?id=1009122 on
mozilla-inbound, which re-enables necko's predictive actions capabilities.
I won't go into the full explanation of it here, you can find the big
information (very little of which has changed in this new iteration) in my
original post,
https://groups.google.com/d/msg/mozilla.dev.platform/tAnuc-J0DbY/snrGsOVW1MAJ
The big thing to note about this landing is that data is now stored in the
disk cache instead of sqlite, which means the predictor (formerly "seer")
should not be causing jank or excessive cpu usage any more (hooray!) This
rewrite also keeps the improvements in page load time seen in the previous
iteration (see previous message linked above for details).
This is currently enabled on desktop and android, and disabled on b2g, as
e10s support is not fully there in the predictor yet. To be clear - this
will not break anywhere e10s is enabled, it's just a no-op for now if e10s
is enabled. Work on e10s support is proceeding in
https://bugzilla.mozilla.org/show_bug.cgi?id=959752 (feel free to follow
along if you wish).
Any bugs you encounter with this feature enabled, please file a followup
blocking 1009122.

Nick,
I just read through your previous post and I'm underwhelmed by the
detail in it. Can you go into more detail about how it "may" issue
speculative DNS lookups/SSL negotiations? It seems to have some privacy
ramifications that I think deserve a more thorough explanation.
For anyone else who's curious, it seems you can disable this by setting
"network.predictor.enabled" to false in about:config (or by using e10s
it seems ;) ).
Thanks,
Patrick
