Q: What is a *usable* free proxy site that you *know* is usable?
(Emphasis on the two highlighted words above: You know it's usable.)

I`m using Freedome VPN and Surfeasy (free and paid version included
with Opera) and can recommend them. Freedom VPN seems to be faster on
my Android. But on the Window PC I already have another, private VPN
running (Hamachi) so Freedome VPN was not an option and I chose the
paid version of Surfeasy for Opera as an add-on.
