Description: Safe, secure, powerful and fully customizable, the Opera Web browser is faster and more secure than other browsers available on the market. Opera delivers robust security and a far-richer feature set than any other Web browser and it's free.
Opera is the Web pioneer that delivered tabbed browsing in 2000, and Opera 9.2 features lots of other great tricks for quick navigation, including Speed Dial, a quick way to put all of your favorite daily sites at your fingertips. You can also take, save and trade Notes attached to any Web site while browsing, or Create Search shortcuts from any search field on the Web. Opera 9.27 is super fast and free, secure and stable, and offers lots of great tools for Web Developers.
If you are looking for more of a Stealth Portable Opera check out OperaTor or check out Opera Portable by Kejut those sites both offer a good portable opera, I recomment OperaTor if your looking for more privacy, but you will have to sacrafice some load time for it.
