Embedded YouTube videos sometimes don't show up on Firefox, whatever Mac I am using. Instead, I just get a white space with an exclamation mark. Refresh the screen, and the clip might appear correctly, but it might not. At best, it's hit and miss. My theme is White as Milk.
I do not get this problem with Safari. ... For various reasons, I prefer to use Firefox.
This has only started recently. I am using OSX 10.6.8 and Firefox 4.0.
Is this a known issue? Any fix?
The blog I need help with is davidderrick.wordpress.com.
