Rated 5 out of 5 stars

So good so far. But I want to ask which country code working with stealthy? European country seems to work fine but when I enter Asian country it become random country not the one I enter.

This review is for a previous version of the add-on (1.1.1.1-signed.1-signed). 

Available countries change constantly and when there are not proxies for the country that you ask for we provide one for somewhere else, in Chrome's version you don't have that problem as it has a list of the available countries in a given moment, that will eventually be on the Firefox version too.
