Why would a random browser extension take it upon itself to snoop on your traffic to ensure that the websites you’re using can’t be used for illegal things, and then intentionally break it if it detects something it thinks it’s illegitimate? That’s a huge overreach. There’s no “legal reasons” that would justify a breach of privacy like that. It’s just malware at that point.

No, I think this is just a bug. Especially since people have reported that the extension breaks other websites too.
