Within about 30 minutes of installing this, 2 of the accounts I logged in with (social media/streaming) were compromised and passwords changed, locking me out of them. Could be a coincidence, but the timing was too much. STRONGLY recommend NOT using this add-on.

it is wretched

Deceptive, full of backdoors to spy on you. Should be removed from Firefox immediately

Не знаю, как там в других странах, но из России я ни к одному серверу так подключиться и не смог.

Ограничение по работе, временное. В бесплатной версии требует переход к платной. Ограниченный выбор стран. Дешевка.

Какие то входы, пароли требует. МУСОР!

it never worked

The premium server is worse than the free server
And the PC version has so many bugs it's impossible to make it work.
Buy this product, and you will waste at least 5 hours just trying to make it work.

требудет зарегистрироваться и платить

Доступные серверы только для преимума. И это неточно. Требуют регистрации, пробуют получить адрес ящика, зачем-то серверы посортированы по странам, но по факту по фиг, какую страну выбрать: соединения НЕТ.
