Opera 9.5 gives Firefox 3 a run for its money

Two of the most popular Linux browsers were unveiled this month after years of development -- the open source Firefox 3 and the proprietary Opera 9.5. Opera's launch a week before Firefox was like any other launch, unlike Firefox's much publicized world record attempt. But Opera 9.5 is no less revolutionary than Firefox, matching its open source rival feature for feature, from security-related enhancements to improved multilingual text rendering.
