Opera浏览器起初是一款挪威Opera Software ASA公司制作的支持多页面标签式浏览的网络浏览器，由于新版本的Opera增加了大量网络功能，官方将Opera定义为一个网络套件。
Opera支持多种操作系统，如Windows、Linux、Mac、FreeBSD、Solaris、BeOS、OS/2、QNX等，此外，Opera还有手机用的版本，在2006年更与Nintendo签下合约，提供NDS及Wii游乐器Opera浏览器软件；也支持多语言，包括简体中文和繁体中文。
Opera还提供很多方便的特性，包括Wand密码管理、会话管理、鼠标手势、键盘快捷键、内置搜索引擎、智能弹出式广告拦截、网址的过滤、浏览器识别伪装和超过400种,可以方便下载更换的皮肤，界面也可以在定制模式下通过拖放随意更改。下载一个大约10M的扩展以后，它甚至可以让你用语音控制以及阅读网页（英文）。而以上的这些，包括右键菜单都是可以由用户自定义的。
Opera支持包括SSL 2/3以及TLS在内的各种安全协议，支持256位加密，可以抵御恶意代码攻击、钓鱼攻击等网络攻击。而其网页渲染速度也是当今速度最快的。它支持W3C标准 ，此外它还可以作者模式和用户模式让有经验的使用者控制浏览网页的结构和字体等。
Opera浏览器软件特性：
高速度
Opera充分利用缓存机制，快速载入页面。Opera在各项测评中得到相当好的成绩。它使用独家排版引擎Presto。
2007年9月4日，Opera推出了采用Kestrel排版引擎的9.5测试版。
多功能且小巧
Opera功能众多，除了浏览网页，还包括POP邮件，IRC聊天，RSS浏览，语音控制浏览，阅读文本（不能读中文），还能添加各种控件，比如计算器、汇率转换器、天气预报、小游戏之类的。最新版中还有BT下载功能。不带语音数据和Java的安装程序大小一般不超过4M。
高灵活性
Opera具有相当多的人性化功能，方便用户使用。它支持多页面浏览，支持换肤、鼠标手势、页面缩放以及自定义页面格式。鼠标手势是Opera首创的功能，还有快进、自动页面登陆、自动填写信息、会话管理、笔记、快速设置等功能。它还内置了各种搜索引擎，以及合理的快捷键设置。
高定制度
对界面的定制 ,Opera 做得极其方便, 而且用户不用担心, 把界面搞乱. 用户可以定制丰富的按钮, 以及工具菜单和搜索列表. 还有 Opera 首创的鼠标手势以及键盘快捷键。这些备份起来也十分方便,用户只须要备份相应的.ini 文件, 当重新安装时只需要选择相应的菜单和工具栏以及鼠标手势快捷键即可, 用户还可以用其他人编写的菜单, 工具栏等. Opera 还内置了一些样式表, 用户可以改变网页的字体结构等.
高安全性
Opera更新十分频繁，每次发现浏览器缺陷后都会尽快升级。最新的Opera 9完美支持包括SSL 2/3以及TLS在内的各种安全协议，支持256位加密，可以抵御恶意代码攻击、钓鱼攻击等网络攻击，提供对Cookie的细节控制，可以一键清除计算机上保存的所有个人浏览信息，还可以自动进行安全性升级。从secunia.com中我们可以了解到Opera的安全性一直以来均高于Internet Explorer、FireFox等浏览器.
多语言
Opera采用界面加载语言包的形式，理论上可以有任意语言版本的Opera。

Here is to the first snapshot of the new year!
A new year mean faster performance. Well, I think it should. We have done some optimization of preference and web storage file saves. Which greatly improves performance for websites with lots of storage data like Twitter and many of our extensions. Problems with storage corruption for sites and extensions on exit should also be resolved.

We have also upgraded two internal components: auto-update and settings protection. When you get this snapshot you will help us test the new new auto-update mechanism for our next snapshot. I t should be more reliable in every environment and make sure there aren’t any problems blocking users from upgrading. The new settings protection may reset your search provider to the default setting. This is done in an effort to prevent third party applications from changing some user-settings without consent from the user.

一个网络浏览器。功能齐全，安全性高。浏览速度比 IE 要快很多。
安装原版后，退出 Opera 原程序，执行这个汉化补丁，然后重新启动 Opera 即变成简体中文。如果没有变成简体，请来信告诉我情况。我会改进补丁包。汉化完成后，您应该自行设置某些 Opera 参数，让它更适合于您。
补充说明：目前的 Opera 的字体显示技术很先进，用户不用自行调整了。
注意：此补丁汉化目标为 12.14.1738.0 的 32 位英文版。
