The Chrome browser is already a handy doorway to Google's cloud-based services, from Google Drive and Photos to the Docs editors. But through Chrome extensions you can customize the popular web browser by adding tools and notifications to make your browsing life easier, more productive, and safer.

Chrome browser extensions are small apps that let users extend what Google's browser (Windows and Mac) can do. An extension often adds an icon to Chrome's toolbar, in the area to the right of the address bar. Extensions can show you everything from the number of unread Gmail messages to which trackers a webpage is using and help with tracking protection and managing third-party cookies. Extensions can monitor prices on retail websites, watch your grammar, send web content to your Kindle, help capture screenshots, and manage passwords.

You can search for and install extensions through Google's Chrome Web Store. The store organizes extensions into 12 categories, including photos and productivity. Find the extension you want, and then click the "Add to Chrome" button to add the extension to your browser. The web store also offers browser themes and apps, including games.

Once you've added an extension for Chrome, you'll see its icon displayed to the right of your address bar. Rearrange extension icons by clicking and holding one and then dragging it to a new location. You can also hide an extension by right-clicking its extension icon and selecting "Hide in Chrome Menu." View hidden extensions by clicking the three vertical dots at the far end of the row of extensions, and remove an extension by selecting that option when you right-click an icon. And finally, when you click an icon, you can choose Manage Extensions to see a complete list of the extensions you've installed. You can also see all your extensions by clicking the three vertical dots over to the right of the icons and selecting "More Tools and Extensions."
