For months now I have been testing the German beta version of Firefox's eBay extension. I have been extremely impressed by its stability and features and it has rapidly become one of my "must-have" extensions. I buy (and sell to a lesser extent) on eBay all the time and that extension is extremely handy. You get a pop-up notification when you have been outbid, when the auction is about to end and much more.

Now it seems that the extension has come out of beta as eBay is now advertising it. I can only find the British version and the German version. If anyone can find a US version, please post the link here.

If you use eBay and Firefox, this extension is a must-have.
