In Edit/color settings mine is set to sRGBIEC61966-2.1 and prefer embedded profiles.
You say you're opening your images through Camera Raw... Check the color profile you've selected to convert into, it might still be the default Adobe RGB, which if viewed without color-management will usually look desaturated.
You might find it helpful to set Camera Raw to convert directly to sRGB...
This makes no sense as described, except if they are indeed Adobe RGB (as Noel suggests). But you say sRGB. Some information is missing.
Where is it desaturated, exactly? In Photoshop, or the web browser, or both? What browser?
How are these files opened and processed, exactly? Are they jpegs, or a raw format from the camera? Are they opened through Camera Raw (ACR)? How are they saved? Are you by chance using Save For Web?
One pitfall I can think of concerns jpegs processed through ACR. Those edits are stored in metadata that are not recognized elsewhere, until the file is actually saved. If you just click "Done" and close the file the edits are recognized in Bridge and ACR, but nowhere else. You need to either click "Save", or open the file into Photoshop and save it there.
And the snapshot has little significance if you don’t provide the »as should be«-version, too.
What are your Color Settings (instead of typing them up please post a screenshot on this Forum with the Insert Image-button/camera-icon)?
