Datasette Stops Serving rel=next Link Headers to Firefox

Datasette author Simon Willison found that Firefox automatically prefetches the next page of rows based on the link rel=next HTTP header, causing wasted rendering and bandwidth for the vast majority of visitors who never click through. He changed Datasette to stop sending that header to Firefox for HTML pages. The underlying Mozilla bug has been open for 24 years, and his own 2002 blog post on the behavior had been entirely forgotten.
