There are other discussions about this but http://forums.mozillazine.org/viewtopic.php?f=38&t=1551645 gives you a few clues that OTHER.COM names have to be allowed.
I use Firefox (always up to date, currently 3.6.8) and within the past week or two, any and all downloads on CNET Download.com stopped working in this browser. When I paste the url into Chrome, those same downloads work just fine.
I haven't made any changes or added anything to prevent this (I do have the NoScript add-on running, but everything on CNET is set as "allowed")...I have even tried adding exceptions in the security and pop-up tabs in Firefox, but that doesn't fix the problem.
Any help? I would really like to continue using Firefox and CNET, which has been a great combo for me for some time now!
