Opera 8.52 for Macintosh is available for download
My favorite OS X browser, Opera includes pop-up blocking, tabbed browsing, integrated searches, and advanced functions like Opera's built-in email client, RSS Newsfeeds and IRC chat.
You can also customize the look and content of Opera with a few clicks of the mouse.
Key features in Opera 8

Opera pioneered tabs and pop-up blocking. With tabs you can open multiple pages within the same application window. Opera lets you control whether to block all pop-ups, or open only the ones that you have requested.

Search your favorite sites, for example Google, eBay, or Amazon without having to go to their Web pages. Use the integrated search window or search directly in the address field using shortcuts (e.g. writing "g Opera" in the address field will search for "Opera" using Google). demo
• Opera security dialog
Stay away from spy-ware, viruses, and other malicious applications that silently attack your computer while you are surfing the Web. For example, Opera displays security information inside the address bar, located next to the padlock icon that indicates the level of security present on a site. Opera 8 also provides protection against phishing attacks and automatically checks for security updates. More about security
