The Opera 5.0 release, for Mac OSes 7.5.3 to 9.2, comes six weeks after the release of Opera 6.0 for Microsoft's Windows operating system. The company also has browsers for the Linux/Solaris, Symbian and QNXOS operating systems.
"Opera has clearly gained a significant foothold in the Windows market as the best pure Web browser," Dean Kakridas, vice president for desktop products at Opera Software, said in a statement. "And with the help of a growing loyal user base, we hope to achieve the same success on the Mac platform."
The 5.0 browser boasts a number of features already familiar to users of Opera for Windows. These include a quick way to turn Web images on and off, a way to organize multiple Web site windows, a feature for zooming in on Web pages up to 1,000 percent, and a way to store passwords securely.
The new browser, available for download from the company's Mac page, is available in a free, ad-sponsored version. Those who download it can get rid of the ads for $39.
Opera's browser for Mac OS X is undergoing its final testing, or beta, phase. The Opera 5 Beta 3 for OS X is also available for download from the Opera site.
