In the browser wars for market share . Microsoft Internet Explorer still commands the lead but market share is fading, While the new kid on the block Google’s “Chrome” breaks the 10% barrier and Opera barely exist anymore. Chrome gains popularity because of its light use of the the deskspace fas loading and aggressive stance on HTML5 while Firefox is has high hopes in the promised 4.0 release. Internet Explore continues to fade away in popularity because the newest versions will not run on other operating systems or even on older Microsoft operating Systems.
Firefox seems unable to be able to capture the lost IE share, probably because its gaining a reputation of being bloated and slow. Firefox and Chrome run on most versions of Apple, Windows and Linux. There is a lot of competition and investment for software that no-one will ever pay for.
