I'm on Firefox and it did nothing for me. The popup came up so fast between me refreshing and hitting escape.

Alternatively, you can disable JavaScript on the website. That lets me view it.

I would suppose it interrupts the page load after streaming the HTML and before loading and/or executing the cookie banner‘s javascript, meaning the content is there but the cookie banner will never open.

On Chrome on desktop it stops the (slow) javascript running which is what actually loads the blocker. You need a fast finger.
