Microsoft Corp. (MSFT) will unveil its new version of Internet Explorer as it tries to stem losses in the browser's market share.

Microsoft will unveil the test version of Internet Explorer 9 in San Francisco, Bloomberg News reported. The new version will load pages faster and support HTML 5 technology.

Internet Explorer has been steadily losing market share to browsers such as Firefox, Google Inc's (GOOG) Chrome and Apple's (AAPL) Safari.

"Based on developer buzz, it seems tech enthusiasts are more excited about IE 9 than any version of IE in recent times," Matt Rosoff, an analyst at research firm Directions on Microsoft, said. "We might start to see IE regain some market share from Firefox."

Internet Explorer currently has 60% of the browser market, from 74% two years ago. Firefox has 23% of the market, while Chrome has 7.5%.
