Wasn't Mozilla the open source version of Netscape Communicator, rather than a rewrite?

  You're probably right. An earlier version of Netscape was a rewrite. Mozilla was a refactored version of Netscape (to remove closed-source dependencies)

  Netscape 4 was pre XUL. Mozilla browser was Netscape 6 with XUL 'hotness' and massive UI lag. Firefox was stripped down and fast (though XUL is apparently still around).

  Mozilla started as a big rewrite of Communicator 4, which was then open-sourced at an early stage. It wasn't great because it concentrated a bit too much on rewriting underpinnings (XUL, Gecko etc), resulting in a relatively poor UI. Eventually a skunkwork project was started to drop all non-browser components and focus on user UI, and that became Firefox.

  Initially Netscape Open Sourced Mariner that was on track to becoming the engine of Netscape 5 and was an evolution of the engine of Netscape 4. Netscape 4 lacked proper DOM support and proper CSS support. (Project to add DOM support was called Perignon, IIRC.) Netscape had purchased another company called Digital Style. Their layout tech became Gecko but was called Raptor and NGLayout before being renamed to Gecko. Mariner / Netscape 5 was canceled and Mozilla migrated to Gecko, which was used in Netscape 6. SpiderMonkey survived the transition from Mariner to Gecko and is used in Servo, too.
