Step 1: Identify the Right Capital One Extension for Your Needs

Before we dive into the installation process, it's crucial to understand that Capital One offers a couple of key browser extensions, each with a slightly different primary function:

  • Capital One Shopping (formerly WikiBuy): This is your ultimate savings companion. It automatically finds and applies coupon codes at checkout, compares prices across thousands of retailers, and even notifies you of price drops on items you've viewed. It's designed for finding deals and earning rewards while you shop. You don't need to be a Capital One cardholder to use this one!

  • Eno® from Capital One®: This extension focuses on enhancing your online security. It provides virtual card numbers at checkout, which helps protect your actual credit card details from potential fraud. It also manages these virtual cards for you. Eno is primarily for Capital One cardholders who want an extra layer of security for their online transactions.

So, which one are you looking for? Or maybe you want both! For most users looking to save money, Capital One Shopping is the go-to. For added security, especially with online purchases, Eno is invaluable. Keep in mind that Eno is specifically for certain Capital One cardholders.

Step 2: Ensure Your Safari and macOS Are Up to Date

Before adding any extensions, it's always a good practice to ensure your software is current. This helps prevent compatibility issues and ensures you have the latest security features.

Tip: Context builds as you keep reading.Help reference icon

Sub-heading: Checking for macOS Updates

  1. Click the Apple menu () in the top-left corner of your screen.
  2. Select System Settings (or System Preferences on older macOS versions).
  3. Click on General in the sidebar.
  4. Then, click on Software Update.
  5. If an update is available, click Update Now and follow the on-screen prompts. Your Mac may need to restart.

Sub-heading: Updating Safari

Safari updates are typically tied to macOS updates. So, by updating your macOS, you're usually updating Safari as well. However, it's good to know that Safari extensions generally require Safari 12 or later.


Unlike other browsers that might have their own extension stores within the browser itself, Safari extensions are downloaded and managed through the Apple App Store. This adds a layer of security, as all extensions are reviewed and signed by Apple.

  1. Open Safari on your Mac.
  2. In the top menu bar, click Safari.
  3. From the dropdown menu, select Safari Extensions... This action will directly open the App Store to the "Safari Extensions" category.

Sub-heading: Alternative Method: Searching the App Store Directly

You can also open the App Store directly (find its icon in your Dock or Applications folder) and then use the search bar in the top-left corner. Type "Capital One Shopping" or "Eno from Capital One" to find the respective extension.


Step 4: Downloading and Installing Your Chosen Capital One Extension

Once you're in the App Store, the process is similar to downloading any other application.

Tip: Reading in short bursts can keep focus high.Help reference icon
  1. Locate the Capital One extension you wish to install. You might see "Capital One Shopping: Save Now" or "Eno from Capital One".
  2. Click the Get button (or the price, if it's a paid extension – Capital One's are free!).
  3. The button will change to Install. Click it again.
  4. You may be prompted to authenticate with your Apple ID password, Touch ID, or Face ID (if your Mac supports it). Follow the on-screen instructions.
  5. The extension will begin downloading and installing. Once complete, the button will change to Open.

Sub-heading: Initial App Launch and Setup (Important!)

  • Click the Open button after installation is complete. This is a crucial step! For most Safari extensions, you need to open their accompanying app at least once for the extension to properly install and configure itself within Safari.
  • The Capital One Shopping or Eno app will likely open and guide you through a brief setup process. This might involve:
    • Granting permissions: The app will ask for certain permissions to function correctly (e.g., access to websites to find deals or generate virtual card numbers). Always review these permissions carefully.
    • Signing in or creating an account: For Capital One Shopping, you might be prompted to sign up or log in. For Eno, it will link to your Capital One account.
    • Following any specific instructions provided by the extension app.

Step 5: Enabling the Capital One Extension in Safari Preferences

Downloading and installing the app is only half the battle. You need to explicitly enable the extension within Safari itself.

  1. Open Safari if it's not already open.
  2. In the top menu bar, click Safari.
  3. From the dropdown menu, select Settings... (or Preferences... on older macOS versions).
  4. In the Settings window, click on the Extensions tab.
  5. In the left sidebar, you will see a list of all installed extensions. Locate "Capital One Shopping" or "Eno from Capital One."
  6. Tick the checkbox next to the extension's name to enable it. You may be asked to confirm this action or enter your password/Touch ID.

Sub-heading: Configuring Website Access Permissions

  • Once enabled, you might notice an option to "Allow in Private Browse" or "Edit Websites..." next to the extension's name in the Extensions tab.
  • Clicking Edit Websites... allows you to control which websites the extension can access. You can set it to:
    • Ask: Safari will ask for permission each time the extension wants to access a new website.
    • Deny: The extension will not be allowed to access the website.
    • Allow: The extension will automatically be allowed to access the website.
  • For Capital One Shopping and Eno to function optimally, they generally require "Allow" access to all websites or the specific shopping sites you frequent. However, always choose the level of access you are comfortable with.

Step 6: Verifying the Extension and Starting to Use It

Congratulations! Your Capital One extension should now be active in Safari.

  1. Look for the extension icon in your Safari toolbar. This is usually a puzzle piece icon, or it might be the specific Capital One Shopping (shopping bag) or Eno (Capital One logo or a shield) icon.
  2. Click on the extension icon. This will usually bring up a small pop-up window or menu related to the extension.
    • For Capital One Shopping, it might show you available deals, your rewards, or a search bar.
    • For Eno, it will appear at checkout pages to offer virtual card numbers.
  3. Start Browse and shopping!
    • With Capital One Shopping, visit your favorite online stores. When you go to checkout, the extension should automatically pop up and search for coupon codes. It will also alert you to better prices on product pages.
    • With Eno, when you reach a payment screen on an online retailer, Eno should appear and prompt you to generate a virtual card number.

Troubleshooting Tips: What if it's not working?

While the process is generally smooth, sometimes extensions can be a bit finicky. Here are some common troubleshooting steps:

  • Restart Safari: Close Safari completely (Safari > Quit Safari from the menu bar) and then reopen it.
  • Restart Your Mac: A full system restart can often resolve minor glitches.
  • Check for Extension Updates: Go back to the App Store and search for the Capital One extension. See if there's an "Update" button instead of "Open."
  • Re-enable the Extension: Go to Safari > Settings > Extensions and untick then retick the checkbox for the Capital One extension.
  • Check Permissions: Double-check the website access permissions for the extension in Safari > Settings > Extensions > [Extension Name] > Edit Websites. Ensure it has the necessary access.
  • Reinstall the Extension: If all else fails, you can uninstall the extension (in Safari > Settings > Extensions, select the extension and click "Uninstall") and then repeat the installation process from Step 3.
  • Check Capital One Support: Visit the official Capital One website or their support pages for specific troubleshooting guides related to their browser extensions. They often have dedicated FAQs for common issues.
  • Browser Compatibility: While Safari is supported, occasionally there might be specific website interactions that are optimized for other browsers. This is less common for general-purpose extensions like these but something to keep in mind.
