Microsoft's Explorer loses to open source Firefox

The open-source Firefox browser is continuing to take market share from Microsoft’s Internet Explorer, having captured over 8% of the market.

The open-source Firefox browser is continuing to take market share from Microsoft’s Internet Explorer (IE), having captured more than 8% of the market.

The 8.06% share reached last month was measured by web metrics firm NetApplications and it is continuing to rise, said the company.

NetApplications measures traffic on 40,000 global websites and says Firefox’s share of the browser market, based on users of these sites, rose from 7.38% in April.

Firefox’s gain is mainly at Internet Explorer’s expense, said NetApplications. IE saw its share of the market decline 0.77% to 87.23% in May.

“While 87% market share may seem like market dominance, the numbers are revealing an average of 0.5 to 1% loss of users each month,” said Dan Shapero, NetApplications chief operating officer.

“Firefox is gaining traction with early adopters and its popularity and adoption rate are starting to tap into mass-market acceptance,” he said.

Firefox's increasing popularity comes despite an increasing number of serious security bugs in the browser, which have led to a number of Firefox updates in past months.

The full browser figures for May were:

Internet Explorer - 87.23%
FireFox - 8.06%
Netscape - 1.64%
Safari - 1.91%
Mozilla - 0.58%
Opera - 0.51%
Other - 0.07%
