Reset Your Web Browser
Google Chrome has an option that will reset itself to its default settings. To find this option, open Chrome’s menu and select Settings. Perform a search for “reset browser” and you’ll see the Reset browser settings button.
Firefox also allows you to return it to its default state. To do so, click the Firefox menu button, point to Help, and select Troubleshooting Information.
The desktop version of Internet Explorer has the ability to reset its settings to the default ones. If you’re using Windows 8, resetting Internet Explorer on the desktop will also reset Modern Internet Explorer’s settings.
