What does it mean (to me) when a "certificate" to pirate bay is "invalid"?

OK. That is the first explanation that I *understood*.

1. I went to piratebay.whatever with Firefox 42.
2. Firefox and Avast both expected a certificate for "piratebay.whatever".
3. What came back was a certificate for cloudflares instead.
4. So Avast barfed on it.
5. Presumably, had I not used Avast, Firefox would have also barfed.

Now the $64 question....

Is it safe (so to speak) to go there?
I'm not expecting perfect safety (this isn't a banking site).

But, is it *really* the piratebay that I'm going to or not?


With a faulty certificate (e.g., for a piratebay.whatever when the Web
site is now cloudflares.com), you are at risk, The Pirate Bay site
might have been hijacked.

Pharmaceutical companies claim their drug prices are
so high because they have to recover the costs of developing
those drugs. Two questions:

1. Why is the U.S. paying the entire cost of development while
prices for the same drugs in other nations are much lower?

2. Manufacturers of generic drugs did not have those
development costs. Why are they charging so much for generics?
