Salient point. Dont get me wrong, I use FF reader mode all day long and I sing its praises to all who will listen. But I am using this to access content over Tor when cloudflare would otherwise prevent me from doing so.
I would not recommend for anyone to feed all their browsing to a third party in a way that can easily be tied back to them, but I am using this tool to overcome a specific obstacle when I encounter it and not otherwise.
Maybe I should have described this scenario more completely at the start of my post 🤷
