I added a faq entry about this. Loic does not see how we could detect a specific Netscape version. In this case, the user talks about 4.75. And since Netscape 4.75 is upgradeable, I think it's ok to close this bug. Rabus wrote:

Hi list,

could you have a short look at bug #574596? A user reports some export problems with Netscape Navigator 4.5. My question is: do we really need to work around NN 4.5 bugs? Regards,
