进网站按照教程走手机电脑三端都能用

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.

It's cool addon

Очень быстрый и бесплатный VPN. Рекомендую.
