Possible issue with webRequest.onAuthRequired in latest Chrome

[Tom Riley]

Hi all,

Does anyone's extension use `webRequest.onAuthRequired` that has noticed any strange behaviour with the latest version of Chrome ( 130.0.6723.70 )?

Our extension is used by customers to connect to our proxy servers, but it appears that in the latest version of Chrome, the `onAuthRequired` sequence when the proxy challenges for authentication just gets repeated over and over, meaning the request hangs for 10-20 seconds, or indefinitely.

Using the same proxy servers and credentials, the issue does not appear to happen with the same code in Chromium 125, and the previous (MV2) version of our code in Firefox. The issue also appears to still happen when loading the previous MV2 extension code into the latest version of Chrome. It is hard to be sure though, since the problem is not consistent, sometimes the 407 handshake works after 2-3 times, sometimes it works with no problem.

Thanks to anyone who can shed any light!

Hey Tom

What context are you calling onauthrequired in? A continent script, a background worker, etc?

Hi Patrick,

It's in a background Service Worker.

Thanks! there was an issue back in 11* days of chrome, I will try to find out if there is a regression here.

On a trivial check it doesn’t look like that area was updated recently. If you have the ability to share a reproduction it would be very helpful

OK thanks for checking, Patrick.

This does seem specific to Chrome 130.0.6723.70. I've installed the puppeteer testing version of Chrome 130.0.6723.59 (the previous release) and I don't see the issue happen.

I'll see if I can find a way to share a reproduction.

This turned out to be a problem using our extension when the user has the 1Password extension enabled. It will prevent the webRequest.onAuthRequired process from completing correctly.
