I have a potentially stupid question- I was going to post some pictures that I've already uploaded to Facebook, but since I've always thought/assumed Facebook reduces the quality of photos I uploaded them to Flickr first. However, the colors in the photos on Flickr (or imageshack, which I also tried) look visibly less vibrant than they do in either iPhoto or Facebook.
Edit: I tried looking up the problem, and it indeed does look fine in Safari. But then why do things look fine on Facebook in Firefox?
Edit again: I just installed Firefox 3.5 and it looks fine now. Sorry for my rambling.
