absolutely 100% agree. Vmware is the best way to go in this regard. You will get a fast modern browser and os in a cage and you can save state before you start and revert back to a clean state as often as you like, and the revert process is very fast.
Security wise, i'm not aware of anybody breaking out of the vmware vm. I think there is a strong possibility of breaking out of the UAE vm and taking over the process.
