August 13, 2001
A usability evaluation was conducted with the Netscape 6.1 client on August 8 & 9, 2001. Issues that are relevant to Mozilla, as well as the commercial client, are summarized here.
A total of six users participated, in the evaluation. User experience ranged from intermediate to advance. Overall, participants were able to effectively use the products once they had located them. It was difficult in some cases for the people to find the various products with the menus or from icons that are provided in the interface. Also, there was a significant amount of confusion regarding the difference between the client based products and the web based counter parts that are provided as part of the Netscape website.
The main issues uncovered during testing are summarized below.
