Opera v9.50 Build 9656 Beta

Opera为来自挪威的一个极为出色的浏览器，具有速度快、节省系统资源、订制能力强、安全性高以及体积小等特点，目前已经是最受欢迎的浏览器之一。多文件接口(MDI)、方便的缩放功能、整合搜索引擎、键盘截径与鼠标浏览功能、当机时下次可以从上次浏览进度开始、防止pop-up、 Fullscreen、对HTML标准的支持、整合电子邮件与新闻群组以及让使用者自订接口按钮、skin、工具列等的排列方式，都是Opera多年来备受喜爱的特殊功能。

对于对互联网技术有进一步研究的用户，Opera也是一个不可多得的好工具，包括HTML的标准验证、支持WML(WAP)、可以创建关连窗口、显示窗口尺寸等功能，对于设计网页的工作者助益很大。而Opera精心为视障用户设计的一系列功能，也是一个特点。另外值得一提的是，Opera除了在Windows外，也支持Linux、Mac等桌面操作系统，值得拭目以待。另外在欧美推出的Nokia 9210i当中，也内建的Opera在Symbian操作系统的浏览器，足见Opera在浏览器技术的实力。
