Yet IE9's gains continue to fall short of what's necessary to make up the losses suffered by the company's other editions. In July, IE6 dropped nine-tenths of a percentage point to end at 9.2 percent; IE7 fell by three-tenths of a point to 6.3 percent; and IE8 plunged by eight-tenths of a point to 29.3 percent.
IE6's share was under the 10-point mark for the first time since shortly after its 2001 release. Microsoft has aggressively pushed IE6's demise, telling customers for the last two years that they need to be retire the 10-year-old application.
Another sign that IE9 hasn't turned the tide is that since its March debut, Microsoft has lost 3.1 percentage points of share, while Safari has picked up 1.4 points and Google has gained 1.9 points.
StatCounter, a European rival of Net Applications, also said IE, Firefox and Opera lost share in July, and that Chrome and Safari expanded theirs. StatCounter, which measures usage differently -- it does not weight its data by country, as does Net Applications -- had IE at an all-time low of 42.5 percent, Firefox with 28 percent, Chrome at 22.1 percent and Safari with just 5.2 percent.
Net Applications calculates browser usage share with data obtained from more than 160 million unique visitors who browse 40,000 Web sites that the company monitors for clients. More browser statistics can be found on the company's site.
