How exactly could it obfuscate it? You can see every request in its entirety and if you see a request that you can't read, that's already enough reason to not use it. As for delaying it, it would have to store it somewhere like localStorage, which is just as easily inspectable.

If you're worried about that, loading it in a private window and switching to offline mode, then closing it after you're done makes any exfiltration impossible.
