Tor Browser overrides the Accept-Languages header in the page-layout tests

[cfm]

Description

Tor Browser's anti-fingerprinting protections prevent both profile-based and options-based configuration from overriding the Accept-Language header used to test localization in the Source Interface's page-layout tests.

Steps to Reproduce

1. Run LOCALES="de_DE" make translation-test.
2. Examine the contents of securedrop/tests/functional/pageslayout/screenshots.

Expected Behavior

All screenshots are in German.

Actual Behavior

Journalist Interface screenshots are in German. Source Interface screenshots are in English.

Comments

I tried using Selenium Wire to override the Accept-Language header on the wire, but it conflicts with tbselenium.¹²
