Mozilla's Firefox browser lost market share last month, with Apple's Safari boosted by rising Mac sales..
In January, Firefox accounted for 13.7 percent of the browser usage market, down slightly from 14 percent the month before, according to web metrics company Net Applications. The dip was the first since May 2006. Since then, Firefox's share has risen continually month to month.
"It appears to be a real dip," not a statistical anomaly, said Vincent Vizzaccaro, Net Applications' executive vice president of marketing and strategic relationships. "It's still bigger than November, though, as if Firefox had a little spike in December. Firefox has had minor setbacks like this before."
More conspicuous than Firefox's slip, however, has been Safari's steady march. The Apple browser, which is based in part on the open-source Konqueror, boosted its share to 4.7 percent in January from 4.2 percent in December. A year ago, Safari held 3.1 percent of the browser market.
"The more interesting trend is on the Safari side," said Vizzaccaro. "It looks like it's taking share away from browsers in the Windows environment."
Net Applications, which also tracks web users' operating systems, said that the increase in Safari's share has been matched move for move by a climb in Mac OS X use. In January, the combined PowerPC- and Intel-based Mac OS X share was 6.2 percent, up from December's 5.7 percent. "Both Safari and Mac OS X are heading in the same direction - up," Vizzaccaro said.
Windows XP still has an overwhelming lead in operating systems, however, with 85 percent. Microsoft's Internet Explorer accounted for 79.8 percent of the browser market in January.
Windows Vista, which was launched for businesses in November and hit retail shops on 30 January, had just 0.2 percent share by then, according to Net Applications.
