What is the end of support for firefox versions?

I am compiling a list of unsupported software versions for the company I work for and I was wondering what your policy is on it. For instance do you only support the latest minor release of FireFox or do you support the Major releases as a whole?

Mozilla supports a stable release, currently Firefox 57. Stable has a major version number increment every 6-8 weeks, so any list you're making is going to change often.

Mozilla also supports an Extended Support Release (ESR), currently based on Firefox 52.
