Comments about Mozilla Firefox as an Alternative to Opera
The best-selling original feature of Opera was its built-in VPN. Firefox doesn't have that feature. It is claimed that Opera's vpn is really more of built-in proxy, and it doesn't get you past an IP block anymores like the old one did. Old versions update automatically and there's no going back. I recommend Epic Browser which is free and has a built-in proxy, that when enabled, doesn't leak your IP.
