As you can see above chrome downloads the pages instead of displaying them (in ~1:5 ratio). This happens on Firefox too. It's not my network problem because this doesn't happen with any other sites.
EDIT: While I was adding a comment:
Looks like the site was loading some content via AJAX and this stuff is returned.
EDIT 2: My browser versions: Chrome stable, Firefox stable, Chrome beta. OS: Windows 7.
