used by spammers, SEOs, DDoSer and other automation surfing. If you are not one of them, want to hide your IP, using for this extension in the browser and you can see this page, it says that all your traffic passes through unknown servers specified hosting and it has access to, as a minimum, the developer extension. If it would be unfair, then no problems will be installed on your computer trojan spoof content pages or to use your computer as part of a botnet (eg to embed on each page you visit a couple of dozen hidden iframe-s). If you want to hide your IP, use the VPN, Tor or any other tools for this purpose, and not browser extensions that are on their servers access to all of your traffic (closed sections of social networks, the administration panel, online banking, etc). Вы на этой странице из-за того, что трафик от Вашего компьютера до этого сервера проходит через хостинговые компании Leaseweb, SERVER4YOU, Hetzner, SoftLayer или Amazon. Эти хостинги активно используются спамерами, сеошниками, ддосерами и для прочей автоматизации сёрфинга. Если Вы не из их числа, хотите скрыть свой IP, используете для этого расширение в браузере и видите эту страницу, то это говорит о том, что весь Ваш трафик проходит через неизвестные серверы на указанных хостингах и к нему имеет доступ, как минимум, разработчик расширения. Если он окажется недобросовестным, то без проблем сможет установить на Ваш компьютер троян, подменить содержимое страниц или использовать Ваш компьютер как элемент ботнета (например, встраивать на каждую посещаемую Вами страницу пару десятков скрытых iframe-ов). Если Вы хотите скрыть свой IP, то используйте VPN, Tor или любые другие инструменты для этого предназначенные, а не расширения браузера, имеющие на своих серверах доступ ко всему Вашему траф
