The open-source Firefox browser’s challenge to Microsoft’s Internet Explorer browser is slowing.
Web metrics company WebSideStory said Firefox’s share of the browser market had increased from 6.75% in April to 7.86% this month (September).
The increase of just over one percentage point over five months does not match the rapid momentum initially achieved by Firefox after its launch last November.
WebSideStory said Internet Explorer's market share for September decreased to 88.46% from its 88.86% share in April.
According to WebSideStory, Firefox is now mainly taking market share from other browsers, such as Netscape, Opera and Apple’s Safari.
To come up with its browser market figures, the metrics company monitors usage of thousands of websites.
