Need a rollback to my previous FF version on Mac Desktop, as my sound streams all stutter. How can I do this?

MacOS Sierra 10.12.6, Mac mini, 8 GB RAM. I updated FF and now have lost a critical (to me) legacy add on whtat has no replacement, also my sound streams stutter whenever I only move the mouse or switch a tab. I have reduced memory use of FF to minimum, and allocated all spare memory, but it does not solve the problem

I would like to rollback to the latest FF version that supports legacy add-ons, preferably without losing any bookmarks etc. in the process.

Any ideas on how to do this?
