Send To Gatherer is a Firefox add-on that creates several new items in the context (right click) menu - "Send to Gatherer (New window)", "Send to Gatherer (New tab)", and "Send to Gatherer (Popup)".
Just select any text on a page (hopefully the name or partial name of a card!), right click, select one of the Send To Gatherer options, and it will attempt to open the card(s) in the Magic: the Gathering Gatherer database with the selected method.
