Tested on:
• Browser / Version: Firefox Nightly 123.0a1-20240108213208 / Firefox Release 121.0.1-20231230165955 / Chrome 120.0.6099.43
• Operating System: OnePlus 6 A6000 (Android 11) - 1080 x 2280 pixels, 19:9 ratio (~402 ppi pixel density)

Notes:

  1. Reproducible on both Firefox Release and Nightly
  2. Disabling the ETP makes the cookie banner appear but accepting it doesn't result in the page showing, it is still blank
  3. Not reproducible on Chrome

Moving to Needsdiagnosis.

We're investigating.

This is entirely server-side UA sniffing going wrong. You get an empty HTML doc, only a doctype, with a Firefox Android UA. You can reproduce this with curl,

$ curl -H "User-Agent: Mozilla/5.0 (Android 10; Mobile; rv:123.0) Gecko/123.0 Firefox/123.0" https://www.google.com
<!DOCTYPE html>%

and it seems that this affects all UA strings with versions >= 65. <=64 work.

Since this has now been posted to HN, I'll be locking this thread. This bugtracker is a work place, not a discussion forum.

Cross-referencing the matching Bugzilla bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1873601

We have a patch ready to deploy in a dot-release if needed, but from what it currently looks like, this hopefully won't be needed. We'll share updates here and on Bugzilla when we have something to share.

Since my last message, Google has been rolling out a fix. We've observed the progress over the last hours, and it seems like this issue is fixed for the vast majority of users. I'll go ahead and close this bug as fixed.

I'll also unlock this issue in case there's still a large group of people who still experience blank-page issues on Google Search that can be fixed with a UA spoof. Although, instead of commenting here, I strongly suggest filing a new bug for this, because that's more likely to get picked up by our triage process, as opposed to just sending me a notification that I might see eventually.
