When using Firefox 2.0.0.4 and trying to access links to videos on youtube.com, I'll click the link to the video, but when it loads, it loads it in HTML code.

Now, I've tried a couple of different settings in Zone Alarm Pro, but found no difference. When I SHUT DOWN Zone Alarm Pro, there is no problem accessing the videos on You Tube. When I turn Zone Alarm Pro back ON, I get the above HTML code once again.

Can anyone give me any ideas how to correct this problem? Thanks in advance for the replies.

Operating System:Windows XP Home Edition
Product Name:ZoneAlarm Pro
Software Version:7.0
