See https://www.mozilla.org/en-US/firefox/68.1.0/releasenotes/ Fixes https://www.mozilla.org/en-US/security/advisories/mfsa2019-26/ Basically a copy of what was under www/mozilla-firefox, as 60esr will soon be EOL, and we want to track 68esr in 6.6-stable. As a side-effect, esr now uses pledge like mainline firefox. The bn-BD & bn-IN lackpacks were merged into bn.
