Profile doesn't load when I downgrade from Quantum

I've tried out Quantum and decided I didn't like it (it didn't support most of the addons that I use frequently and there wasn't a noticeable speed boost) so I tried to roll back to a pre-Quantum version (ver 47) but when I did, the newly loaded FF was a clean slate; all the addons, bookmarks, and open tabs were gone. They only came back when I re-installed FF Quantum. I still want to use a pre-Quantum Firefox. How do I do this?

Firefox does not support downgrades. And I don't recommend doing this with any release profile.

These are the risks https://support.mozilla.org/en-US/kb/risks-downgrading-older-version-shar...

I am sorry we could not be more helpful to your question.

Are there particular features that you need help changing that would prevent a downgrade?
