In the error console there's this error:
[Exception... "An attempt was made to use an object that is not, or is no longer, usable" code: "11" nsresult: "0x8053000b (InvalidStateError)" location: "resource://gre/modules/WindowsPreviewPerTab.jsm Line: 322"]
That line is ctx.drawImage(this.canvasPreview, 0, 0); in drawThumbnail.

Duplicate of bug 545077 perhaps?

I'm afraid I don't have time to work on this feature (haven't for years really). That said, this probably isn't a difficult bug for someone to fix if they're willing.
