Predicting that Microsoft will lose market share from month to month isn't especially difficult. Yet it is amazing to see the downfall of what was once a bastion for Microsoft. It appears that Microsoft can't defend IE against Firefox and, as it seems, Google's Chrome. Net Applications now believes that IE has a share of less than 60%, which is about the range that IE had in early 1999, when IE5 was launched. IE is now officially back in the 1990s. Chrome, by the way, is the fastest growing browser, both in absolute numbers and percentages. It is well ahead of Safari and more than tripled its share within 12 months.
