UGH, you're right. Ok, let me explain this. We whitelisted google.com but it was not anticipated that, in the general case, we should really whitelist all subdomains in order not to break sites.

Luckily this was a one-line patch: https://github.com/EFForg/privacybadgerfirefox/pull/63 (though in the future, it is better for the whitelist to have wildcards in the cases where it's necessary).

Thanks for testing. Really helps a lot.
