Quick Sum

Quick Sum 0.1 is an extension for Firefox that lets you quickly sum up values on webpages, much like a Similar feature found in Microsoft Excel. Quick Sum works well with the Ctrl+Click feature of Firefox that allows you to select multiple table cells. Try it out on your online bank Statements or any other PaGE with lots of numbers. Quick Sum also allows you to choose a calculation to use, providing sum, average, min, and max functions.
