Been spending a lot of time on here!
I wonder if it makes any difference if you use sRGB color profile when saving the files. But I cant see how that would help the soft focus I seem to often notice.
It may, I have noticed that some of my greyscale images embedded with Generic Grey will render as if they were embedded with Generic Grey 2.2. Converting to sRGB will be more likely to be compatable but on occasion may not be 100% accurate.
On my end, using Safari 5.1.2 on OSX Lion, this image rendered similarly no matter what program I used and was embeded with VIP's monitor profile.

VIP - are you editing using this profile? If so, you may want to consider using AdobeRGB or some other wide-gamut color space, not because you can see the whole of the AdobeRGB gamut (you can't), but rather because you'll have a larger pallet for your CMS to choose from.
