Internet Explorer [...] has now reached its lowest point in over two years at 82.10 percent. Firefox, on the other hand, has been growing steadily, reaching 12.46 percent market share. Safari holds its third place spot, but sees increasing numbers as well at 3.53 percent.

[...] Safari, while holding much smaller numbers than IE and Firefox, is also becoming nothing to sneeze at. A year ago, Safari had less than 2 percent of the browser market but has almost doubled its numbers since then.
