I've noticed recently that firefox isn't displaying some gif (animated ones) or png images.
for example the image in this post
Browser Tests
The source for it is a different colour in firebug:
Anybody have a clue why this is happening or what that washed-out colouring means?
I copypasta'd the image link into a new tab to see what it was, then the next time i viewed that post it was fine...
Very confusing.
