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’s a shame that Russia has to be Russia because Yandex has some good stuff. I like their maps and street view equivalent (it only works for places like Russia and Belarus but I’ve played around with it out of curiosity) - it’s less clunky than Google’s and it lets you change the year to view streets scenes from different years. If only that could have gone global.
