GREAT!! I use a few different free Firefox VPN add-ons. I've always had this one in the background [pretty much disabled, but still there as a backup] since the early days of Win 8. The main reason was because these guys had: all the no logs privacy declarations, the we don't sell your data etc. etc. - age's ago - before anybody realised that stuff was really important. So security wise 10/10, but in those old days, this add-on was sooooooo slow. I mean like dial-up slow : / *But that seems to have all changed now : ) I used their US servers, just now, today, and my jaw dropped as I reached a robust average download speed of between 2 Megabytes/s + 5 Megabytes/s! Now, that's bloody fast in anyone's books for an Ad-free, Free, Multi country/Server, Firefox VPN addon. Excellent work guys : ) Well done! Thoroughly recommended : )
