Chrome was the only browser to gain significant usage share last month, and it again trounced Firefox.
By the end of April, Google Inc.'s Chrome accounted for 6.7% of the browsers that surfed to the sites that Aliso Viejo, Calif.-based NetApplications monitors for its clients. Chrome boosted its share by 0.6 percentage points, by far the largest increase of any browser for the month, and the second-highest increase since Google launched the application in September 2008.
Virtually all of Chrome's April expansion came at the expense of Microsoft Corp.'s Internet Explorer, which dropped 0.7 percentage points to finish the month at 59.95%, the first time that IE has fallen under the 60% mark. IE's decline was lower than the previous month -- it lost nearly a full point of share in March -- but was still above its average monthly decline.
