I'm a bit confused why anyone would want this, but what the heck: Netscape has released the latest version of its Navigator browser, which appears to be based on Mozilla Firefox 18.104.22.168. It has a different set of (green) toolbar icons and a few unique, but not particularly compelling, features:
Cross-platform - Run Navigator 9 on Windows, Mac OS X, or Linux!
URL correction - Navigator will automatically correct common typos made in Web addresses
Link Pad - Use the Link Pad as a holding area for interesting links that don’t merit bookmarking
FF2 Extensions - Install any Firefox 2-compatible extension
Sidebar - Use the sidebar as a "mini browser" to keep a page in plain sight while you surf through other pages
