Pasting the Wrong address in metamask

I’ve literally just been battling this! Is it an address like this by any chance?

EDIT: Ignore my previous message, after some further digging I’ve found that this is caused by the MM browser extension when you all it FULL ACCESS to any website without requesting it. Turning this off has fixed it for me
