Firefox is already really comfortable when it comes to searching the web. One search box is displayed by default which is great if you want to do a fast search for something. Did you know that there is another way, even faster and better than this one ? Firefox supports so called keyword searches which means that you define a keyword for a certain search engine and can use that keyword to search it without visiting the website of that search engine.
Let me give you an example to clear things up. You may right-click any form field in Firefox and select the menu entry Add a Keyword for this search. Selecting this opens a new Add Bookmark menu which asks for a name and a keyword. I went to ebay.com and did a right-click on their site search. I entered the keyword “e” and the name eBay.
