- Reverted malicious upstream commit
  https://hg.mozilla.org/integration/autoland/rev/a03a9c72d1db3716adffc6968cfb6eb43c6fcd74
  which forces firefox to autoremove yandex, mail.ru, vk search extensions.
  Note: reverting that (and some similar) commit is a necessary condition to
  make firefox obey the search engine settings specified in policies.json.
  Alas it might be not enough. The problem is that firefox is tightly
  integrated with services provided by Mozilla corporation, such as bookmark
  sync, telemetry, captive portal detection, you name it. Reportedly a similar
  malware has been deployed there, thus yandex search extension (or in fact any
  extension) can be removed remotely (that is, without user consent) if the user
  is signed in into mozilla account, sends telemetry data to mozilla, etc.
  Perhaps it's time to make unmozilla firefox (similarly to ungoogled chromium).
- policies.json: use yandex search by default (Closes: #43516).
