Netscape Browser (or Netscape 8) is the eighth major release of the Netscape series of web browsers, now all discontinued. It was published by AOL, but developed by Mercurial Communications, and originally released for Windows on May 19, 2005. Netscape Browser was the first browser of the Netscape series to be based on Mozilla Firefox, as opposed to Netscape versions 6 and 7 which were based on Mozilla Application Suite. Also, Netscape 6 and 7 were Internet suites whereas Netscape Browser (version 8) was solely a web browser.
