Problem: Color Management/Save for Web on Wide Gamut Monitor

Question

Hi,
I've got a problem with color management - I thought I understood it, but it seems as if didn't. So I'm trying to kindly ask for help.
I'm printing, and also trying to save an image for Web.
My setup:
- Win 7, CS 5
- Calibrated Wide Gamut Monitor (eizo cg223w)
- Photoshop set to ProPhoto (I don't want to start a discussion adobergb vs prophoto)
- Save for Web and Devices, Embed Color Profile, Convert to SRGB
- Viewing in Firefox 3.6 with Color Management enabled
Problem:

If I compare the file in Firefox and Photoshop, the Firefox presentation is slightly more saturated - and I have no idea why.
I thought it should work with the above workflow.
Here is a screenshot where you can clearly see a difference (Note: the additional over-saturation here is caused by the wide gammut monitor when taking screenshots, in reality its not as dramatic as that): http://imgur.com/MFPbU but you can clearly see the difference.
I would be very very thankful for any pointers what I'm doing wrong in my workflow!
Thanks in advance,
Christoph

Is this the preferred way?
It's a reasonable and correct way to do it, assuming you want to embed a profile in the images.
Since at least in some browsers and cases the colors selected within the HTML elements must match image colors, one can sometimes make a case for not embedding any profile at all, but that's really looking backwards.  Browsers are moving forward toward not only managing colors in images but also in the HTML elements themselves.  If you want your images accurately portrayed in as many places as possible you're doing the right thing looking forward.
Personally I embed the sRGB profile in my web images, as you are doing.  And I check things primarily with IE and Safari.
Unlike you, I prefer to edit using the sRGB color space, but that's just personal preference.  I find it more convenient to use File - Save As instead of File - Save For Web & Devices, and I get caught by gotchas less often this way.  Your preference ensures you don't lose any colors at the extremes of the gamut while editing and it could easily be argued that that's better, depending on what image products you produce.
As for the article you mentioned, anyone who would set their preferred working space to Monitor RGB or use Proof Colors in normal editing is asking for trouble, and may not understand color management at all.
