1. Sign up to SellerTab for FREE on our site: www.sellertab.com.
2. You will be sent to eBay to sign in to your eBay account and authorize linking SellerTab with your eBay account.
3. Once you do that you will arrive at your control panel. Click on "Install" in your control panel.
4. A pop up window will appear asking you if to allow installing the extension, click on "Allow".
5. In the next window click on “Install now”.
6. Now once you close and re-open your FireFox browser you will immediately be able to see SellerTab in every new tab you open.
