Firefox's worldwide market share hovering near 30%

Mozilla now estimates that its Firefox web browser is now responsible for some 30% of all web browsing.

Yesterday Mozilla released its first quarterly analyst report (PDF), a document which bought together a whole raft of metrics related to the browser.

By number-crunching data from four metrics providers that Mozilla called "reliable sources" - StatCounter, Quantcast, Net Applications, and Gemius - to pull together a worldwide usage figure of 30% for the plucky browser.

On a more granular level, the company also pulled apart the stats on a continental level:

Strongest adoption is in Europe, with usage up at 39.2%. The browser usage for north America stands at 26%.

Other interesting data ... we'll, the tab usage data was an eye opener:

In one recent study, we found that the typical user has between 2 and 3 tabs open at any one time.  And what was the maximum?  Over 600 tabs!
