It is not a browser issue as the color changes become apparent immediately (even in Paint.net's save preview window).
I placed the original test.jpg next to 'I Love Pi''s test.png to make it more clear how things change during the save of the new file (attached here).

I would have agreed with you both until yesterday.
'I Like Pi', I see that you created a test.png from my test.jpg... put them side by side and you'll see that the colors got changed significantly.
Brewster, I've tried both 'Autodetect' and 32-bit for the png settings and the same color changes occur.

PNG loses the quality too (I tried that earlier)
Other tools such as FastStone Image Viewer and Gimp can handle saving this file without losing the quality. In the case of FastStone I get to preserve the quality by selecting what they call a 'Photometric = RGB'

I use Paint.net a bunch and love it.
Today I ran into an odd thing though... I was editing an existing JPG image and was doing some cropping to it and then saving the cropped image. I noticed that the new image was losing significant quality. I have quality set to 100%. Any ideas?
I'm attaching two pictures to demonstrate the issue. One is a portion of the image that I'm starting with, the other is a capture showing how the save operation loses quality... the most obvious portion is the fairly bright red horizontal line in the picture (ends up looking much dimmer in the new image).

So I still think there is room for improvement in Paint.net since the PNGs that can be created are being displayed differently in the various browsers (not Paint.net's fault) and the JPGs created lose accuracy/quality. I'm calling it an improvement since other paint programs have found a way to deal with it.
I'm including screen shots how how two others handle it with no loss of quality (their JPG save options).
