More than one out of 10 surfers use Firefox as a browser, according to a study by web analytics firm OneStat.com. Although Mozilla-based browsers have a total global usage share of 11.51 percent - an increase of 2.82 per cent since April 2005 - Microsoft's Internet Explorer still dominates the global browser market with a global share of 85.45 per cent. Its share has slipped 1.18 per cent from the end of April.

For some unexplained reason, Mozilla's browsers are more popular in the USA (14.07 per cent use Firefox) and Canada (16.98 per cent) than in the UK (4.94 per cent), according to OneStat.com. Its figures come from a survey of two million visitors to sites running OneStat.com's Web site services. JavaScript code on these Web sites is used to detect which browser a surfer is using.

Many mainstream web sites are difficult, if not impossible, to use by surfers who prefer Opera, Konqueror, Mozilla and other alternative browsers. To get around this problem its common for alternative browsers users to try agent spoofing - a trick which allows Opera users (for example) to present themselves to web sites as users of IE. OneStat.com claims the methodology of its survey allows it to factor out this behaviour.

Although OneStat.com has witnessed a steady increase in Firefox usage over recent months other firms report the opposite trend. Last month, web applications provider NetApplications reported that Firefox was losing ground to IE with usage of the open source browser down to 8.07 per cent in July compared to 8.71 per cent in June 2005. Either this was a temporary blip or one or other of web analytics firms is getting its trends in a tangle. We're not sure which. ®
