Version 91.7.1, first offered to ESR channel users on March 14, 2022

Yandex and Mail.ru have been removed as optional search providers in the drop-down search menu in Firefox.

If you previously installed a customized version of Firefox with Yandex or Mail.ru, offered through partner distribution channels, this release removes those customizations, including add-ons and default bookmarks. Where applicable, your browser will revert back to default settings, as offered by Mozilla. All other releases of Firefox remain unaffected by the change.
