If your browser cannot leave a new tab page such as the Chrome one shown above and cannot navigate to another web page, here are a few possible remedies.
First, check if the keyboard or mouse is the issue.
Check if the backspace or other key is stuck. If that is the case, try to raise the key. Failing that, unplug the mouse and keyboard and see if the problem persists. Perhaps a key or short cut is being repeatedly triggered without the user’s knowledge. This can be confirmed by using a different keyboard or mouse.
Second, if it’s an issue with the browser
Other than Internet Explorer, you should save bookmarks into an html file then uninstall the browser thoroughly with an uninstaller tool such as Revo or from the Windows Control Panel. Reinstall the browser and see if the browser still freezes on the new tab page.
Internet Explorer is integrated with the Windows installation and cannot be simply uninstalled. For IE, after backing up desired new settings, configurations, and files, perform a system restore. Restore Windows to the last remembered time that the browser did not experience the new tab persistence problem.
