Суперское решение для того, чтобы полноценно выглядеть иностраноживущим для сайтов. Чтобы проходить капчу CloudFlare - необходимо отключить HTTPS EveryWhere и включить Отпечатки Браузера, тогда всё будет ок. Автоподгонка времени и языков браузера под айпишник и отключение геолокации - мастхэв. Низкий поклон и огромная благодарность причастным, чтоб вас поддержать приобрёл подписку ВПН. Надеюсь, что функционал продолжит расти до более точечных функций и улучшаться нынешний :) например, решить ситуацию в которой функция HTTPS Everywhere влияет на прохождение некоторых видов капчи, а именно, делает её невозможной.

Если разберётесь + используете СВОИ прокси, то отлично

Is Secure Kit Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Secure Kit requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Secure Kit is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
