How can I use a Legacy Extension that 57.0 doesn't support and if not what older Versions of Firefox will support it? Thanks, rh1cm2

My Legacy Extension won't work in 57.0 If you can't tell me how to get it working what older Version of Firefox will support it I would hate to use another browser.

What legacy extension is it?

Generally speaking:

One option would be: Switch to Firefox Extended Support Release (ESR) for personal use. The downgrade is likely to erase your history and you may need to roll back many extensions to older versions. Unless the legacy extension is pretty critical, it may be more hassle than it's worth.
