I downloaded the latest offline installer version of Firefox and it will not run a vital unsigned add-on. I have an older version of Firefox (42.0) that will run it. Is that the last version of Firefox without the add-on signature check? Thanks.

Firefox 42 is the most recent version of Firefox that has been released to the public. If you are running a later build, it is probably either nightly, beta or Dev edition. If you have an unsigned add-on you need to run in those editions, you can disable the requirement by setting xpinstall.signatures.required to false in about:config.
