Move firefox to the esr releases
Almost a week ago I suggested moving to the -esr version of firefox.
This will pick up new security fixes in the 68 series, whilst ignoring churn (e.g. firefox-69.0.2 which appears at this point to only affect 69, and the move to a newer rust for firefox-70.
Whether or not we do this, the next expected releases (68.2.0, 70.0) will require either a new profile, OR invoking firefox for the first time after the change with 'MOZ_ALLOW_DOWNGRADE=1 firefox' (optionally add -P if you already have multiple profiles and don't want to create another.
So far, nobody has commented on the list so I intend to act on this when the next security release arrives. Unless in the meantime someone can point out what is likely to be lost by staying behind the curve in BLFS.
