Ars Technica Reviews Mozilla
Aglassis writes "This Ars Technica review gives mozilla 1.0 an overall score of 7/10 (9 for Gecko and 6 for the browser). The major detractor was the user interface, since it didn't feel like a Windows application. This was probably due to a poor understanding by the authors of XUL. Overall they say that mozilla would make a good substitute for IE 6 but there is no major reason to switch over."
The point with most (all) MSIE-exploits is that you have to visit a page that has an exploit.
No, the page can visit YOU via the HTML email feature of Outlook Express, Outlook, and even Eudora in some cases. Until very recently, scripting and ActiveX were enabled by default for incoming emails on most mail clients.
