Been trying to find a fix for this, but all I seem to be getting from searches is people having problems with their Wordpress site's code XD
Have you tried viewing the page in IE? If it shows up fine there you may need to reinstall Firefox. My guess is either that update messed up or some of Firefox's add-ons might be the cause *shrugs*
I tried both chrome and IE, neither worked.
I have no clue what this could be if it isn't the browser.

Really sucks because the only place I can see comments is in the comments feed thing to the right.
