Opera Software has released the final versions of its two mobile web browsers, Opera Mini 5 and Opera Mobile 10. Both browsers have been available since September 2009, but Opera has spent the intervening months applying user feedback before releasing the final versions on Tuesday. Rather than adding any new features, Opera has fixed bugs from earlier versions. Some of Opera's key features, such as tabbed browsing, password manager and speed dial, were already available. Opera Mini is the company's free lightweight browser. Mini 5 is available on BlackBerrys, and Android, Windows Mobile and Java-based handsets. Opera Mobile is a paid-for browser that contains more features. Mobile 10 is available for Windows Mobile and Symbian S60-based handsets. Across fixed and mobile as a whole, Opera is the fourth most popular browser behind Internet Explorer, Firefox and Google Chrome, with 4.3 percent market share.
