How do I get items into JBidwatcher from (Safari, Chrome, Firefox, IE, etc.)?

If you are viewing an item on eBay, the address bar generally has a small icon (known as a 'favicon') at the leftmost part of the address bar. Drag that to JBidwatcher and drop it, and it should add the item to the tab you're currently viewing. (If you're viewing the 'complete' tab, it should show up in the 'current' tab.)

If you are viewing search results, you should be able to drag the link to the item to JBidwatcher. Generally dragging the linked title, or thumbnail is best.
