You’ve really got to check out Web Search Pro, a Firefox extension that actually adds a few hot features to Firefox searching.

A new and inovative way to search the web: Drag & DropZones, just drag text on any website, and drop it in one of your 16 fully customizable DropZones, and your search will be started

The “DropZones” actually pop up visually when you drag text, so you can easily make sure you’re searching using the engine of your choice.

The hotkey support in this Web Search Pro is also excellent, so you can set hotkeys for each search engine you use regularly, select text (using the mouse or quick type and the keyboard) and press a hotkey to launch a search. Or, you can press the hotkey without text selected and you’ll get a popup you can type your search query into!

He has buckets of search engines already configured, and you can suggest more or make your own … which is great … but since there is an Open Search format for describing search engines already, why do people keep inventing new formats?
