It opens in foreground. I like background but it has no option that I can choose.

excellent. work as designed. right click and boom, all selected links become tabs. I think this works on most non-dynamic www pages.

Still works fine.

I like the simple user interface. Unfortunately, the tool doesn't work everywhere. For example on this addon page or on Google News it fails to show the context menu topic or to open most of the links. (Maybe, this affects dynamic web pages?)
