I am disappointed with Quantum & have gone back to a previous version using System Restore [Win7 32bit].

I have turned off updates Settings>Options>Firefox Updates>Never But I have had to do yet another Restore to get back to the original version of Firefox

Am I missing somewhere [else] that you can turn off/stop Firefox Updates?

Thanks for your help. Richard F
