8-31-24: the best free vpn addon. more stable than the rest. Not a PITA to use like the others, reliable. But too slow and not enuf free IPs. I've tried them ALL and there is not really a top notch vpn offeted by mozilla, not free at least. Browsec comes closest. Rest are a PITA to use can't connect, break connections and other unreliable behavior not seen with browsec. The guys at browsec seem to know what they are doing unlike all the others.
7-29-24; there are no good free vpn addons. Browsec is the most reliable and stable of them, but it is too slow.
I thought I found a new good one. I won't mention the name as I don't want it to be flooded with new users. The worst of the bunch is adguard vpn. I THOUGHT I have found a good one in cyberghost vpn but it was not and ony works on certain older browsersnewer browsers cannot connect. ALL OF THEM have frequent disconnects that probably reveal your home ip, so they are not really helping with privacy. Browsec would be great if they could increase the speed X2. I'm not gonna pay to find out.
10-20=23: browsec servers are getting more flaky. Slow of sometimes cannot bring up GI tochange vpns requiring on and off or reinstall. some sites are banning their vpn IPs. not enuf free choices and thruput often too slow.
3-17-23: best free vpn addon. exceedingly easy to use and connect. you don't spend all your time trying to get the damn thing to connect and work as with the other "free" vpns. They have begun spamming you with ads and hijacking your browser to do so, but not too bad. Limited selection of IPs for free but they added ENgland a step in the right direction. Good free vpn, use it a lot.
12-17-22: good free, really free vpn. Stable. Fast connections, does not leak dns. small number of countries but they are mostly good. so far best free vpn addon
11-3-2022: one of the best free vpns in easy use and install. Refreshing after going thru all the crap the other "free" vpns inflict on you. Still limited in IPs but at least they work most of the time unlike adguard vpn.
simple easy to connect vpn, no registration BS, no email required just connect. FAST and simple interface. Blocks other vpns when activated and I believe block connection is vpn Ip is broken somehow protecting your privacy. Biggest downfall is small list of vpn ips under free plan, I think 5?

Only 4 servers.

Mediocre. Recently it stopped working altogether.

Не требует обязательной регистрации, включается за пару кликов - однозначно 5 звёзд

Отличный VPN! Спасибо всем кто работал над этим

Works well!

This VPN is going down more and more often, browsing the Internet is becoming impossible, what are users paying money for? :(((

worked fine for years - Aug/15/2022 got internet speeds below 1MB/s! slowed down everything on FireFox.
