Google Chrome widened its lead over Firefox last month, according to new desktop browser stats.
For April, Chrome accounted for 17.9 percent of all desktop browser Web traffic recorded by Net Applications. That number was up from 17.5 percent in March, the first month that Chrome surpassed Firefox, at least based on Net Applications' data. In contrast, Firefox saw its share dip slightly to 17 percent last month from 17.2 percent in March.
Over the longer haul, Chrome has gradually been gaining more traction, while Firefox has been slipping. Net Applications' stats from April of 2013 showed Google's browser with a 16.3 percent piece of the pie and the "thrilla" from Mozilla with a 20.3 percent share.
Still dominating top place last month was Microsoft's Internet Explorer with a 57.8 percent share. IE's share has been fluctuating over the past few months but is still higher than the 55 percent seen in April of 2013.
Microsoft currently has more to worry about than IE market share, however.
A new zero-day bug has left IE vulnerable to hackers. The bug is so severe that US and UK security agencies have advised people not to use Internet Explorer for now. Microsoft updated its advisory about the flaw on Monday with suggestions on how to better protect the browser. But the company has yet to issue a security patch to fix the problem.
Net Applications' stats differ from those of other Web trackers. StatCounter, for example, has long shown Chrome dominating over IE, Firefox, and the rest of the pack in Web traffic. Why the difference? Each Web tracker uses its own somewhat unique methods and sources to determine Web traffic data.
For example, Net Applications counts unique visitors per day versus page views and has a stronger presence in certain countries than do other Web trackers.
