This is the best add-on that I've ever used on firefox. It's REALLY convenient and easy to use. It's a most creative way to search on the Web. Imagine you could simply drag your keywords to the grid automatically shown and release the mouse key, the search is done. So fast! I'm a language leaner and I use it more often to look up new words on different dictionary or reference sites (like Oxford dictionaries, Cambridge, wordreference forum, etc.) as there are more online dictionaries now available. This one is part of the more comprehensive add-on Web Search Pro (Mr. Captain Caveman is a developer of that add-on) which includes not only most features of Drag & DropZones but also many other useful search functions. There's an option of this add-on to choose between switching or not to the page opened after a search and personally I perfer to choose not to switch so that I need not wait for the page to load fully and I can continue my work on the current page without being disturbed. This is very good and considerate!
This great add-on is one of the very reasons that I have adhered to using Firefox. It really has helped me a lot when I search on the Internet. I'd really like to express my thanks to the developers. Thank you! This is the best add-on!
