This would be great, if it worked. I tried to install it today, and instead a Mozilla Plug in Search was installed, but hooks to a Bing search were added to the registry. When I try to install it now, I get the error- "Firefox could not install the search plugin from "https://addons.mozilla.org/firefox/downloads/file/54407/bing-20090601.xml?src=search" because an engine with the same name already exists." And yet Bing does not appear on any plugins or the search drop down. I tried doing "Firefox -safe-mode" and remove everything but my bookmarks, and it still fails. What's even worse, is the Bing search WAS installed on my copy of Firefox, and somehow now won't appear as a choice. Since it doesn't work,ONE star.
