Details

(Keywords: meta, Whiteboard: [necko-triaged])

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36

Steps to reproduce:

Use a <link rel=prefetch> in multiple browsers.
See https://github.com/whatwg/html/pull/8111 and new failing tests in https://github.com/web-platform-tests/wpt/pull/35707.

Note that this is part of an ongoing standardization effort of an existing feature, so it's understood why this wasn't a "bug" earlier.

Actual results:

The headers are different. Chrome sends Purpose: Prefetch. Firefox Sends X-Moz: Prefetch.
Accept headers are different. Chrome sends something with signed-exchanges, Gecko sends /.

Expected results:

According to the new spec PR and WPTs:

  • Prefetch should send a Sec-Purpose: Prefetch header.
  • Accept header should be equivalent to navigation
  • When consuming prefetch, Vary: Accept should be ignored.
  • Prefetching same-site documents should work.

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Core & HTML' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Per comments in https://github.com/web-platform-tests/wpt/pull/35707 the tests are flaky in Firefox (but not in Chrome/Safari).
