Debian follows the extended support releases (ESR) of Firefox. Support for the 78.x series has ended, so starting with this update we're now following the 91.x releases. Between 78.x and 91.x, Firefox has seen a number of feature updates. For more information please refer to https://www.mozilla.org/en-US/firefox/91.0esr/releasenotes/ For the oldstable distribution (buster) one more final toolchain update is needed, updated packages will shortly be available as 91.4.1esr-1~deb10u1 For the stable distribution (bullseye), these problem have been fixed in version 91.4.1esr-1~deb11u1. We recommend that you upgrade your firefox-esr packages.
