Add-on wont work on mac. Stops all connections and never connects to a server. Wont even show the drop down window when clicking the icon. The desktop app works fine and I will have to stick with that. Extension 1 star, desktop and mobile app 500000000000 stars.

Using daily for a couple of years now and absolutely love it. Does every thing you could wish for in a VPN & Ad-blocker. You need this. Don't buy into the hype on the expensive apps that can give you nothing more and in a few cases less. Very Highly Recommend!

so far so good

Works well, easy to use. Pretty fast for a VPN. Worth it1

it cool

July, 2022. Another dishonest lame "free" vpn. Forgets your login data and then puts you into an endless timeout trying to login. Then if you post a negative review which they richly deserve they will block your access to creating a new account after they lost your old data. Bunch of wankers who cannot program their way out of a paper bag and using the same GUI, which is crappy, slow and unresponsive since their inception probably because they cannot program a new GUI. From memory their speed was always slow and made even slower by the long time it takes them to log you in. THen you must give them youR ACTUAL email address defeating any chance you might have had for privacy. Just another worthess "free" vpn and you get what you pay for. Very small selection of "free proxies" and you have to hunt for them because their gui is so crappy and unresponsive. There is ONLY ONE good vpn free and I aint telling here which one it is. Good luck cuz they all suck save that one and even that one you have to pay if you want very many countries. NONE of them have residential ips so most sites will block you once they see your using a proxy. I guess you have to pay through the nose to get back to the way the net used to be 30 years ago from it's sad state today. An FFox admins you don't have to keep reminding me that I have to download ffox to use it's extension,I already know that, but my reviews are intended to benefit mozille,not evil google
FEB 15, 2021-cannot find our asses with both hands in the dark and a flashlight=cannot find tab. Bullshit time wasting another lame "Free vpn" all these crap vpn extensions, they must recruit from the local homeless shelters.
feb 7, 2021: This company does not listen to reviews or try to fix what's wrong with their add-on. Still the same terrible GUI, hard to navigate, hard to find free proxies, unstable connections. Really don't know why it is rated highly. I am using a competitor free proxy now haven't used windscribe in quite a while but keeping it as backup.
jan 24, 2021: stopped using it. there are NO GOOD FREE VPNS. I've tested them ALL and they ALL suck. This one GUI is very hard to use, slow hard to navigate, free servers difficult to locate. Another lame VPN what else is new.
too much trouble to use it. Hard to connect. User GUI is difficult to use-slow,non-responsive, hard to select. Often have trouble connecting. Lacking sufficient free proxies-hard to use it for free. Found a better vpn free that does not have these problems.
