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.
Bugzilla: 1759009 - Update Distribution Config
lemmy.ml: Firefox v98.0.1 removed Yandex search option and used misleading bug name to hide it
It would help if both had different names and not just “Mozilla Corporation” and “Mozilla Foundation”.
Lol well said.
