What are the disadvantages of netscape navigator?

Netscape Navigator, once a leading web browser, faced several disadvantages that contributed to its decline. Its performance was often slower compared to emerging competitors like internet Explorer, particularly in rendering web pages. Additionally, Netscape struggled with compatibility issues and lacked support for modern web standards, making it less appealing for users and developers. Lastly, its proprietary nature and high cost for advanced features hindered its adoption in a marketplace shifting toward free and open-source solutions.
