firefox does unauthorized update

more options

I have Firefox 40 installed and don't want to update Firefox so I have it a checked to not do auto updates so that it stays on version 40, but Firefox does this unauthorized and unwanted update to version 41, to me that's a form of malware, how can I install version 40 AND NOT have it update to a newer version. If this can't be done then I will just have to uninstall Firefox and refuse to use it in the future.
