It’s easy to add. If you already have Firefox 2.0 or higher installed, download and install the companion just like any other extension. After installation, you will be asked to restart Firefox.

If you do not have Firefox 2.0 installed, you can download a single file comprising the Firefox browser and the eBay companion.

The eBay Companion will open in a sidebar in your Firefox browser.

If the Companion sidebar is not open, click on the eBay toolbar button or open the sidebar. Click on the “Connect to eBay” button. You will be taken to eBay’s secure authorisation page where you are asked to enter your eBay username and password. Once entered, the Companion will automatically connect to eBay everytime you open your browser.

Click on the menu drop down button to the right of the eBay toolbar button. Select “Options…”. Click on the “More” tab and check “Disconnect companion when I close Firefox”.

Firefox Companion for eBay works with any type of computer that has Firefox installed on it. This includes Apple Mac, Linux and Windows platforms. You must have administrative rights to add the Companion to your Firefox Web browser.

We plan on open sourcing as much of the source code we developed under the MPL as possible. We still have some work to do in terms of licensing and code review before we do so, and we'll get to that shortly. However, the graphics, trademarks, certain functionality and the APIs keys used to build this Firefox Companion that have been licensed from third-parties will not be released as open source.
