免费的用不了 可以试下这个 邀请十人可以获得永久免费http://adsabc.net/2kv9k

http://adsabc.net/2kfkq这个亲测好用

Не работает. Вообще.

Nothing works when this vpn is running. Pages take forever to load then just don't load. I have vpns on Vivaldi and Opera that work fine, and slow nothing down. The 2 stars are for being free, having no sign up and having good country options available.

http://adabc1.net/2hp7b我以为是广告 确实能用 我自己在用的

这个扩展已经没办法使用了，推荐后面这个，亲测可用，香港线路非常快，邀请别人可以获得免费时长，大家帮帮我吧，谢谢了。http://adabc1.net/2gm7r

smooth and easy browsing, maybe this is best free VPN extension on firefox. I'll recommend this to others.

Truly free and efficient, not like other "free" VPNs wich are not free. So this is the BEST.

it doesnt work often if cache is cleared. needs to restart browser everytime I clean my cache , cookies or histories in firefox.

Never had any problem with this vpn doesn't slow down my pc at all gives you plenty of options. Thank you Максим.

Ingen information om Hovedkontor. Browsec krævede en læsning af et "Review" baseret på en sendt mail. Det er dårlig stil af Mozilla, at acceptere "ukendte" tjenester. Det bør være et krav, at bevise ens Hovedkontor, og derefter oplyse det tydeligt for alle Firefox (og evt. andre browsers') brugere.

When 100+ tabs are opened and suspended in firefox, uses several GB of of RAM for some reason. about:memory shows millions of allocations of some image:
