No, the Mozilla suite was based on Netscape 4, the &quot;Communicator&quot; suite -- totally &#x27;90s.<p>We did Firefox as a pirate ship within Netscape and made it the lead product&#x2F;project when we spun out Mozilla Foundation. See the roadmap update that Dave Hyatt and I wrote in 2003:<p><a href="http:&#x2F;&#x2F;www-archive.mozilla.org&#x2F;roadmap&#x2F;roadmap-02-Apr-2003.html" rel="nofollow">http:&#x2F;&#x2F;www-archive.mozilla.org&#x2F;roadmap&#x2F;roadmap-02-Apr-2003.h...</a><p>The Mozilla suite had become SeaMonkey and was a separate and tertiary project (after Thunderbird, after Firefox).<p>This was not &quot;research&quot; (I&#x27;m a founder of Mozilla Research along with Andreas Gal and Dave Herman, btw). This was our one and only shot at making a come-back. By 2003, the &#x27;90s suiteware craze was over.
