I usually search Google from the URL box of Firefox. So yesterday when I typed analytics for opening Google analytics directly from Firefox address bar, surprisingly it redirected me to a new page hosted by OpenDNS. OpenDNS aims at speeding up internet by improving DNS response and to provide security against phishing and other scams. But if enabled, in most cases it becomes a real headache by blocking proxies, advertising websites and redirecting Google search feature on Firefox URL box to their advertising page. There are few methods to remove OpenDNS hijack from Firefox address bar .
