You sure about that? I ask, because ActiveX is an Internet Explorer only thing, so unless you're using something like IE Tab, you should never see ActiveX notifications in Firefox. Also, never assume any download from any site is safe. Every single file you download should be treated as suspicious no matter where you download it from. It is always possible that someone managed to quietly compromise the CNet Download.com servers and tamper with files. So always be wary no matter where you get the file from.
Do I accept the ActiveX?
I have said 'No' twice, and the download stalls.
Can I assume that all CNet downloads are safe?
