The Firefox browser continues to rack up incremental market share gains against Microsoft’s Internet Explorer, but security concerns may be taking their toll as the growth rate continues to slip.
Web site measurement and marketing company WebSideStory on Tuesday said that as of April 29, IE fell a percentage point in domestic share to make up 88.9 percent of browser usage, while the Mozilla Foundation’s open-source Firefox browser rose just over a point to 6.8 percent.
The slackening of Firefox’s growth could mean that the browser has converted a substantial proportion of its natural constituency, thought to be early adopters and the technically savvy. It could also show that the browser’s widely publicized security flaws have begun to undermine the foundation’s argument that people should switch from IE to be safer.
The Mozilla Foundation warned against assigning too much importance to falling growth rates, and said the Firefox security profile still bested the competition’s.
