This add-on does NOT currently require an account or email address. It does NOT throttle your download speed, (unlike Browsec), and the daily download limit is about 2.5 GB, which is pretty generous for a free vpn. I haven't read the privacy policy terms so there could be issues there. The choice of countries is a bit surprising and IP checks don't seem to match with countries listed. That aside for a fast & free vpn with good/decent download allowances this is my #1 choice. Hoxx is a close #2. (They have better locations but a much smaller download allowance).
