How to Reinstall Chrome Extensionsby Amanda Rumble
Extensions in Web browsers increase functionality, expand on entertainment, show the news or place games directly in your browser. You can install, uninstall and customize the settings for your extensions. If you have problems with an extension in Google Chrome and need to troubleshoot it, you can begin by uninstalling and reinstalling the extension.
Open Chrome and click the wrench icon to the right of the address bar.
Click "Tools," then select "Extensions" to open the extensions page listing.
Click "Uninstall" beneath the extension you want to remove. Click "Uninstall" on the pop-up to confirm the uninstall.
Open the Chrome Web store and type the name of the extension into the search bar at the top of the page.
Click "Install" to install the extension back to your browser.
