A report from Net Application indicates that for the first time ever, Firefox lost some marketshare last month. Apple's Safara got a 0.5 percent boost.
In January, Firefox accounted for 13.7 percent of the browser usage market, Aliso Viejo, Ca.-based Net Applications said, down slightly from 14 percent the month before. 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," said Vizzaccaro.
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.
