That depends, my information could be out of date, but a couple of years ago I had that problem too, depending on whether or not I attached the color profile to the JPG while exporting from RAW. At the time too, browsers were not always displaying photos with color profiles attached.

For me personally, I edit and shoot in sRGB, and don't attach the color profile to the exported photos. When I view them in different browsers, programs they look the same and the print out great too (MPix.com). That may not work for everyone, but it does for me.
