Какой же вы VPN, если сразу сходу требуете предоставить вам мой email? Вы кто такие, чтоб я вам его давал? Мне нужен от вас VPN и всё. Сведения собирайте с других. Сношу к чертям.

говнище полное, не работает. пидарасы требуют указать личные данные, чтоб мать твоя сдохла нигер

It's not "completely free" because there's a premium part which has most countries in, and which were before accessible for free. But the free part works great too, and has the country I personally need. Still 5 stars for this, because most other VPN extensions don't work at all, so this is the one I'd recommend especially for linux.

Shame! So greedy!

i'm sorry, your add-on isn't good enough. it's working good but expensive Upgrade (1 week= $4). not recommended, i don't trust it anymore... because my credit card cannot pay for unwanted add-on.
and what is "Free forever"? i think everyone should upgrade it every week - year.
it's scam.

It's cool addon
