Summarize this article:

Go to any one of the following proxy sites:   Hide.Me - https://hide.me/en/proxy   ProxySite - https://www.proxysite.com/   ProxFree - https://www.proxfree.com/   Whoer - https://whoer.net/webproxy   Hidester - https://hidester.com/proxy/  You may have to try several proxy sites before you find one which isn't blocked by OpenDNS. If none of the above proxies work, try searching for a proxy by typing best online proxy 2018 (or similar) into a search engine. This text box is usually in the middle of the page, though you'll find it near the bottom of the page if you're using ProxFree. This search bar functions like a built-in browser address bar. Type in the address of a blocked site (e.g., www.facebook.com) that you want to access. This button's appearance will vary depending on your chosen proxy service (for example, you might click Browse anonymously), but it will usually be below or to the right of the text box.  If you're using the ProxFree proxy, you'll click the blue PROXFREE button. You can also just press the ↵ Enter key. Your site should load like it does when browsing on an unrestricted computer, though it may take longer to load due to the proxy's server location.
Open a proxy service. Click the proxy site's search bar. Enter a blocked site's address. Click the Go button. Browse your site like usual.
