I have the Mac OS X 10.11.6 version and need the older Firefox back. All my bookmarks are gone now. And, I cannot find the old file. Please help me restore it to a version I can run on this computer.

This does not solve my problem! It is just the same information I could find on my own. I want my previous version re-installed.
