It is unlikely that Mozilla Firefox 1.1 will be available in March as promised.

Lead engineer for Firefox Ben Goodger has admitted that he was a bit "unrealistic" in his predicted date, and claims in his Blog that the delay is not due to his move to Google.

"It is due to us needing to ensure the 1.1 release is of identical quality and scope as the 1.0 release – that means a period of testing, the localization system needs to be brought back online, etc. These things are done by more people than just myself, so quit with the wacky speculation," he insists.

Goodger started working for Google on January 10. He said: "My role with Firefox and the Mozilla project will remain largely unchanged, I will continue doing much the same work - with the new goal of successful 1.1, 1.5 and 2.0 releases. I remain devoted full-time to the advancement of Firefox, the Mozilla platform and web browsing in general."

Firefox was first introduced in February 2004. Take up of the browser has been good in the light of conrerns over the security of Microsoft's Internet Explorer. It held 3 per cent market share at the end of October, according to WebSideStory.
