Blog Freezes in Firefox

I have absolutely no idea why this blog's homepage freezes when loading in Firefox since this morning.
Maybe this happens only in my Firefox configuration and others fare better?
As I am not the tech-wizard to find out or correct the mistake I kindly refer you to use Safari or Opera browsers meanwhile. All works fine there.
Don't ask me about Softmicro's Internet Explorer as I use a Mac.
UPDATE: All back to normal again.
