The issue:

Android users with Firefox can’t access Google Search (including intl sites and localized domains like google.de, .co.uk, .com.br). Instead, they see a blank page.

Cause:

A server-side bug on Google’s end related to User-Agent (UA) sniffing, which serves an empty page to newer Firefox versions.

Affected versions:

All Firefox versions on Android (>= 65) including Mobile 121.0, Nightly 123, and older.

Chrome not affected:

The bug is specific to Firefox.

Solutions:

  • Use a different browser (Chrome, etc.) or search engine (DuckDuckGo).

Advanced users can:

  • Change Firefox’s UA in developer settings or with add-ons.

  • Request the desktop version of Google from Firefox settings (region-dependent).

Status:

  • Problem identified as critical and escalated.
  • Still unresolved at the time of reporting.

Additional notes:

  • Disabling Firefox’s Enhanced Tracking Protection doesn’t fix the issue.
  • Some users report google.co.in loading the desktop site instead of mobile.

    Interesting, from Germany the Google homepage loads normally but shows the old version (while the search results page uses the new version). Either they partially fixed it, or Firefox in its beta version already works around the problem in some way.
