1. We add ssltunnel here: http://hg.mozilla.org/mozilla-central/rev/4c6a0f776c32 2. From here https://developer.mozilla.org/en-US/docs/Modifying_Mochitest_SSL_behavior it shows how to modify ssltunnel, but there is no obj-dir/build/pgo Please help.

Looks like Bug 1002545

It's definitely bug 1002545. We're currently debating exactly how to proceed with this. Until then use the workaround (or apply some of the patches on that bug, if you know what you are doing).

Bug 1002545 Comment 1 works for me.
