Which of the following is not a supported browser for Sage Accounting?

Sage Accounting is designed to work seamlessly with modern web browsers that support the technologies and functionalities required for the application to operate effectively. Among the choices, Netscape Navigator is considered an obsolete browser, no longer supported or used in modern web standards. Developed in the 1990s, Netscape Navigator was one of the first widely used web browsers, but it has not been updated for a long time and lacks critical functionalities that contemporary web applications demand.

In contrast, Mozilla Firefox, Google Chrome, and even Internet Explorer (although less favored now due to it being phased out in favor of Microsoft Edge) are all current, actively maintained browsers that can handle modern web technologies. Therefore, they are suitable for running Sage Accounting, making them viable options for users. Using unsupported or outdated browsers like Netscape can lead to compatibility issues and hinder users' experiences with the software.
