Just launched I guess. You seem to be able to get it from:
Basically you would be able to do the following:
Never miss a bid
You’re always securely signed in so you can check out your eBay progress whenever you like. Customise your alerts and get the heads up when an auction you’re bidding on is about to end.
Once you are signed in, the eBay button in your browser means you’re always only a click away from eBay! The eBay button opens and closes the eBay Companion sidebar and provides quick access to popular eBay bookmarks.
eBay Companion Sidebar
The eBay sidebar contains all the information that you need to make your eBay trading super-quick and easy. You can instantly check on your buying, selling and feedback status. Everything you need from My eBay is at your fingertips. Take advantage of the quick search bar and shortcuts to eBay My World, your feedback and popular eBay bookmarks.
eBay Alert Box
The Alert Box means you get important eBay alerts when you need them. If an item you are watching is about to end or you have been out-bid you’ll be notified right away by the Alert Box that appears on the bottom right corner of the browser window.
eBay ‘Glow’ Alerts
For less urgent information — such as eBay bidding up on your behalf — you’ll enjoy the convenience of ‘Glow’Alerts. When the eBay logo in the Firefox browser glows, you’ll know instantly that there are changes to your items; open the sidebar to see the items that have changed.
You have total control on what alerts you receive and how you receive them. Customise your experience in the preferences section.
Never miss the eBay action. No matter where you’re browsing, and whatever you’re doing online, you can get an at-a-glance update on all your eBay activities: watching, buying or selling.
Detailed Tooltip Information
Each item has basic information listed, such as the number of bids and current price it is selling for. You can get more information about the item by hovering your mouse over the item to get the number of watchers (if you are selling), seller’s feedback (if you are buying) and other critical information.
Your eBay information is updated at regular intervals. The refresh rate is increased intelligently as watching, bidding and selling items near their end time.
Quick Access to Item Actions
You can quickly access contextual actions for your items by right clicking on any item. For example, you can view a seller’s feedback page, or remove a watched item from My eBay.
You’re safer with the Firefox Companion. You’ll know you’re on a genuine eBay or Paypal page and not a spoof site or lookalike. When you’re using Firefox you’re also at less risk from pop-up ads, spyware and other web threats.
eBay and PayPal Site Verification
eBay and PayPal padlock icons appear on verified eBay and PayPal sites indicating that it is safe for you to sign-in using your eBay username and password.
For extra security, you can activate Account Guard, which warns you if you enter your eBay or PayPal passwords on sites that are not verified as being official eBay and PayPal sites.
