Opera Software has released version 11 of its flagship Web browser to the general public. New features include “tab stacking,” which allows users to combine multiple tabs into a group. New additions include increased support for HTML5 and geolocation. Opera 11 is available as a free download from the Opera website; it requires an Intel-based Mac running OS X 10.4 or higher. It is, for example, the only browser available on Nintendo’s Wii and DS devices, with a market share of about 2 to 3 percent.”]
