The difference may be your display profile being used in a color-managed app like Adobe products vs a browser or other application that isn't color-managed.
There may be a problem with your display profile or the white-point of the profile is very much different than what your monitor is currently set to.
Have you calibrated your display with a hardware calibrator?
that's what i figured (no i haven't used a hardware calibration tool) and seeing your confirmation i took another look and realized that "Color Settings" isn't listed under "Preferences" where i was looking but is its own separate menu / dialog.
so yeah, i just made the adjustment and it seems fine now.
thanks for the tip, next time i'll look harder
Made what adjustment exactly?
Your problem is a bad display profile. The other applications aren't color managed and don't use the profile at all, so they're unaffected.
The way to fix that is to use a calibrator to make a new profile, but since you don't have one use sRGB. Set the profile in Control Panel > Color Management > Devices:
Relaunch PS/Ai so that they can pick up the correct profile at startup.
