But you will be fighting a losing battle, unless you turn off
automatic add-ons update. Add-ons that are converting to the new api
will update if you don't, and then they won't work with the old api,
even on the older firefox version. And there will be no way to
downgrade them because there is only a single version in the Mozilla
repository, the latest.
Ok, I found a copy of FF-56 and I am using that now:
# rpm -Uvh /home/bobg/Desktop/firefox-56.0-5.fc27.x86_64.rpm
Apparently I had a moment of foresight and saved a copy!
"turn off automatic add-ons update." That might explain what happened,
one of the add-ons proudly announced it had updated yesterday. I will
make sure they are all set to not update automatically.
I will save your suggestion for future use though. Also I hope that
Firefox will eventually be able to use the add-ons I need, I check that
periodically but in the meantime will continue to exclude firefox from
my routine morning updates.
