Why does Netscape Navigator crash?

Netscape Navigator 3.0 came in two versions, Standard Edition and Gold Edition. The latter consisted of the Navigator browser with mail and news readers and a web page WYSIWYG composition tool integrated into it. The extra functionality only made the software program larger, slower, and more prone to crashes, and the decision to integrate all these features together was widely criticized. But this integrated version became the only version when it was renamed Netscape Communicator in version 4.0; the product's name change (Netscape CEO Jim Barksdale insisted that Communicator was a general-purpose client application which contained the Navigator browser) diluted its name recognition and confused users.
