Older Firefox can not validate PDF 1.9 Oct 10 update
I use several older versions of firefox ver. 40 - 48 and 52.
Update to PDF 1.9 Oct 10 2017 firefox ver 40 and 48 cannot validate new version while 52 does.
I find no link to rollback to previous versions. Is there a way to load a previous version?

Hello,
It is not possible to load the previous version. We switched the addon to the new extension API that is not supported by older Firefox versions.
