I use a Firefox keyword to directly search MDN, simply so I can avoid W3Schools who always occupy the top spot in results. For those who aren't aware, right click any search box and select 'Add a keyword for this search', set it to something short and then in your URL bar type: "<keyword> <search term>". So to search MDN for the span element I'd type "mdn span".
