You could try a bookmarklet to do that. Set up a bookmark on the toolbar called "No AI" or something, and instead of a URL starting "http..." put
javascript:document.location=document.location+"&udm=14"
Clicking that will add that text to the current URL and reload the page.

Works in Firefox; I don't know if it works in Chrome any more.
