# How do I add SnapWidget to the Firefox Facebook Container?

> Facebook Container blocks Facebook and Instagram sign-in on other sites. Allow snapwidget.com in the add-on to connect your account.

Facebook Container is a Firefox add-on from Mozilla. It keeps Facebook and Instagram apart from the other websites you visit, so their sign-in windows do not work on other sites. If you use it, you cannot connect your Instagram or Facebook account to a SnapWidget widget until you allow snapwidget.com.

**1. Go to SnapWidget**

In Firefox, go to [snapwidget.com](https://snapwidget.com) and log in.

**2. Open Facebook Container**

Click the Facebook Container icon in the toolbar. The icon looks like a fence.

**3. Allow the site**

Click **Allow Site in Facebook Container**. In **Allow Facebook Tracking on this Site?**, click **Allow**.

**4. Connect your account**

Reload the page if Firefox does not reload it for you. Open your widget and click **Connect** (or **Reconnect**) next to **Username**.

To remove snapwidget.com later, click the fence icon, click **Sites Allowed in Facebook Container**, and remove the site from the list.
