StatCounter data suggests that, on a global basis, the number of people using Chrome exceeded those who were using Firefox last Sunday. Chrome beat Firefox with a market share of 26.22% versus 26.16%. It's not much and it was just one day, but it is a significant event as Chrome has caught up with Firefox on weekend days.

Chrome has substantially higher market share on weekends than during the week and the current data implies that the browser needs about four to six weeks to catch up with any number on a weekend on an average market share basis. If this trend holds up, then we should be seeing Chrome match average Firefox market share by mid- to end-November.

For the first half of the month, Chrome averaged 24.85%, which is more than 1.2 points up from last month, while Firefox is slightly down to 26.68%. IE has fallen for the first half of the month below the 40% mark and was estimated at 39.99%.

Chrome market share is, just as it is the case with all other browsers significantly fragmented across the world. In North America, for example, Chrome share is only 20.01%, while it is at 40.82% in South America, according to StatCounter.
