Firefox only: Snap Links enables you to open multiple links in new tabs just by dragging a box around them.
For example, say you want to check out more than one link from the results of a Google search. With Snap Links, you click and hold the right mouse button and drag a box around the links (which get highlighted with red boxes for easy visibility). When you release the button, presto: All the selected links open in new tabs. Of course, this works with any links, not just search results.
Brilliant. Simple. Insanely useful. Add this to yesterday's sweet Tab Scope and you've just given Firefox two big kicks in the productivity pants. Snap Links is free; it works wherever Firefox does.
