"AOL's focus on transitioning to an ad-supported Web business leaves little room for the size of investment needed to get the Netscape browser to a point many of its fans expect it to be." Netscape development director Tom Drapeau wrote.

AOL acquired Netscape in a $4.2 billion deal in 1998. In 2003 the Mozilla Foundation separated from Netscape and AOL with its former parent providing a $2 million dollar parting gift.

Netscape had been based on Mozilla code since Netscape version 6 appeared in 2000.

Netscape Navigator 9

Netscape Navigator 9 (Beta 1) was released in June 2007. It is based on Mozilla Firefox 2.

Some of the new features in Navigator 9:

Mozilla Features: Since Navigator 9 is based on Mozilla, it has all the latest Mozilla features.
URL Correction: Navigator 9 will automatically correct common typos in URLs.
Link Pad: A new sidebar feature that allows you to save links/URLs that you want to visit later without cluttering your bookmarks.
Extension Compatibility: Navigator 9 will let you install extensions that are compatible with Firefox 2.
Sidebar Mini Browser: Bookmarks and links can be open in the sidebar.
Resizeable Textarea: Drag the bottom-right corners of text fields in forms to add more typing space.
Tab History: Opening a link in a new tab will give the new tab the same history as the source tab.
OPML Support: Navigator 9 supports importing and exporting your bookmarks in OPML format.
Combined Stop/Reload button: To save space in your toolbar, the stop and reload buttons are combined.

Netscape 8

Netscape 8.1.2 was released in September 2006.

Netscape 8 allows you to adjust the security level (Java, JavaScript, cookies settings), and also allows you to switch to use Internet Explorer's engine to render pages when necessary.

New features in Netscape 8:

Site Controls (dual rendering engine)
Multi-Bar (dynamic toolbar)
Form fill/passcard
Live Content
Improved tabbed browsing
Adware & Spyware protection
Dynamic Security Center

Netscape 7

Netscape 7 is based on open source engine (Gecko) and fine-tune of Netscape 6.

Netscape 7 has been reported very stable and fast.

Netscape 6

Netscape 6 was released in November 2000. This version was the first Netscape browser with powerful support for CSS and XML.

Netscape 6 is based on open source engine (Gecko), while Netscape Communicator 4.8 used the engine that was originally released in late 1994.

The Netscape Problem

Netscape's 4.x series of browsers had a poor support for CSS and no support for XML.

It took Netscape nearly three and a half years after the release of 4.0, to produce its next generation browser. This delay has clearly hurt Netscape's possibilities to dominate the browser market.

Our browser statistics are showing that Netscape is losing the browser war.
