I’m having the same trouble with my site. I don’t know if it happened after I posted the YouTube video that’s the latest post, but it was in the same time frame. I think it happened after I upgrded to 2.3.3 It displays right in Safari and IE but not in Firefox.
I downloaded and reinstalled Firefox, but it made no difference. I cleared the cache, and that made no difference either. Deleted cookies, still no difference. So the problem seems to be with WordPress and Firefox interacting, rather than just Firefox.
I tried it on a PC as well as another Mac, and no help.
Help?
Thanks,
