TBB shows SSL observatory popup

Getting this popup surprised me a lot, and TBB users will get it by default since the addon upgrades by itself. I don't think too many people know what an EFF is outside the US, not even my computer-savvy friends over here do, and the popup is scary. We should probably pre-configure TBB to not have that popup show up and not transmit certificates to EFF.

What do you think about that?
