I get the message:- Oops... It looks like something is not right

If you are seeing this page it is because your browser has failed some security checks. You may still be able to browse our site to find the feature or store you're looking for.

The Tesco website works OK with Edge on the same machine and Firefox 127.0 on another machine. I think this is a known problem is there a fix/work around?
