> When I start typing ebay, I want "tab to search ebay".
You can configure Firefox to do this with a single checkbox. Go to Settings, click Privacy & Security on the side, go down to the Address Bar section, and make sure that "Search engines" is selected.
When I do that, I can click in the address bar (which brings up the drop-down), type "ebay", and then you'll see "Search with eBay" appear below in the drop-down, and then a single Tab puts it into eBay search mode.
I think that's just because the ebay search engine is installed by default? They want this to work for any site with a search engine they've ever visited - at least, that's how it works in Chrome, IIRC.
