VS2008 asp.net spits out gibberish, possibly wrong encoding issue.

Question

Hello,
I have inherited a project, it was originally written in VS2005.
I have made a few changes, but all are design.
Now when I run the project using the visual studio's web server, in IE8, the page shows up just fine, however in FireFox 3.6.3, I get gibberish (a full page of this):

�I�%&/m�{J�J��t��$ؐ@�����iG#)�*��eVe]f@�흼 ��{���{��;�N'���?\fdl��J�ɞ!���?~|?"~������˓7����t�.���WO���� m߽��{'w�>}�4������x'}��Ŵ�{���G�G�]=�{���j|uo\�w߼��Pv���

My setup: Windows 7 Proffesional (All patches)
VS2008 SP1 (I think all patches)

Thank you for your help!

Resolved! Pages had this tag: <%@ OutputCache duration="n" varybyparam="none" %>

Removing this fixed the gibberish.
