I'm having this same problem with my netbook running with FireFox, but with Internet Explorer that "Feature" section works fine. Don't know if it's a Java update that cause this. The odd part about that is, my desktop has the same exact add-on and there is nothing wrong with the site in both FireFox and Internet Explorer.
For my netbook, I've tried the following and they all don't work
-Disable all-add ons
-Tried in Firefox safemode
-Create a new profile
-Uninstall flash, and update the latest flash
-Clear all history with CCleaner, but that don't matter as I've set FF to clear all data every time FF closes.
This is really bothering me. It works in IE and Chrome, but not FF. If this isn't fixed soon I may need to go somewhere else for my hardware news. It is bad enough that they are always behind, but not even showing me their latest stuff on my browser of choice? Come on.
