New and useless "last versions" service

Hi.
In my company they use Firefox version 47. I am an employee and I can not update the network. Until today it was no problem. Every time I needed an addon for example…

I went to the section “Version history” and took the version that worked in my browser.

But today (November, 28) I see that you have cut the section, leaving only the last sub-versions of the current version. That “service” is worth nothing. If a browser does not accept the current version, it does not accept the previous sub-versions of that version either. What is really needed are the authentic “previous versions”, or at least the best sub-version of each of the previous versions.

I hope that something can be done to leave the service as it was.

We recently disabled all legacy versions on the site, and they’re not coming back. They haven’t been supported for a long time (just as Firefox 47).
