Color Shift in Web Browser

In the thread here. It was noted that the color shifted when viewed in photoshop (simple copy and paste). I tried it myself and sure enough the bird has less red and more blue. The image is a screen capture of the bird being viewed in Firefox side by side with Photoshop. Then I placed color samples at approximately the same point and you can clearly see the difference numerically as well. (I tried various points and the photoshop image was always less orange). The image is in sRGB color space so it should look the same on the web as well as Photoshop. What gives? Curious to find out why the big color shift.

This is odd, I downloaded the images as well, opened it in PS, then took a screen shot of the side by side comparison of the image in firefox (left) and PS (right) - and I don't see the color shift! The color picker (5x5 and 11x11 average) reports a variation of a few points only)
