Mozilla officially released Firefox 3.5 on Tuesday. The new version of the popular open source web browser has attracted considerable attention and is already seeing rapid adoption. It was downloaded over 5 million times during the first 24 hours. This falls short of the record-setting 8 million downloads that Firefox 3 had during its first day, but it still reflects the intense enthusiasm of the browser's fans.
Firefoxr's popularity has rapidly climbed over the past few years, bringing it up to between 20-30 percent of the global browser market, according to various Web analytics firms. Based on data collected from 850,000 web sites, tracking firm whos.amung.us says that Firefox 3.5 by itself now accounts for roughly 2.5 percent of the browser market, more than the total marketshare of rival Opera.
