Understandable, I had it break once during opening a pop-up third-party website while verifying a credit card transaction - very annoying indeed. But through some tinkering managed to catch and whitelist the third party site later (it was timing out so no easy feat) and haven't had similar problems in a while.

You can just disable it for some sites, or play around with their trackers to see enabling which fixes your website. I've seen it break some shopping sites too, but that's been mostly on rare occasions for me.
