You can go here, https://koji.fedoraproject.org/koji/packageinfo?packageID=37 download the version you want, and install it with dnf -C downgrade [downloaded package name] from within the directory where the downloaded package is.
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.
Thanks,
Bob
