2- where might i find earlier releases of 40.x?

3- if i install 40.x in path /var/lib/yum/plugins/local/, will i be able to roll back.

any offers for questions 2 & 3?

Short answer: Don't.

Long answer: You're trying to install arbitrary versions of firefox with known vulnerabilities. You're also using something that isn't supported in CentOS and possibly built against a distro that doesn't have the same build environment and base libraries. It sounds like you've already got a bunch of local customizations that could possibly be preventing a working web browser.
