Instead of going to Chrome, I think you should consider moving to the better alternative to Firefox, Pale Moon. It has all the same mindset of decent Firefox, XUL compatibility (and an oath to never use WebExtensions), and other features.

I was interested in Pale Moon, but you just convinced me to skip trying it. Sandboxing is top important, and WebExtensions are rather important there.
