Hi Damien,
Upon your recommendation, I've been using Firefox for a year or so and I have had no more color issues with my images. But for the last week or two, every time I upload an image using my Firefox browser, whether it be to Dropbox, Facebook, etc. the colors are very oversaturated and have a color cast. I've already followed the instructions on this post: http://www.damiensymonds.net/art_tsfb000.html and everything was correct so I don't know why I'm having this issue. When I view the images on Safari, the color looks correct. Please help me, I'm at my wit's end! I'm attaching a screenshot of an image that was viewed in Firefox and the same image viewed in Safari. Thanks in advance.
