Web Browser Color Management Questions

I have read the color management threads in this forum as well as researching the topic on the internet.

From what I understand, there are 4 major components to color management (excluding printing):
1. Calibrated Monitor
2. Using Color Management Aware Applications to Edit Photos (like Lightroom and Photoshop)
3. Using Color Management Aware Applications when Viewing Photos on Your PC.
4. Using a Color Management Aware Browser (such as Mozilla Firefox) when viewing your photos over the internet.

However, I still don't understand something (probably because my head is spinning from information overload):

If IE is not a Color Management Aware browser, why do the colors in photos from others in this forum and over the internet appear great while the colors in my own photos appear muted?

I could understand it if the colors on all photos on the internet looked muted when using IE, but it's only my photos that look muted (to me at least) in IE.

The colors look as they do on my PC when I view my own photos on the internet using FireFox.

It sounds like your photos might be in a colour space other than sRGB?

When exporting in LightRoom, under File Settings, the Format is set to JPG, the Color Space is set to sRGB, and the Quality is set to 100. In PSE 9, the Color setting is set to "ICC Profile: sRGB IEC 61966-2.1 .The muted color occur in IE whether the images are exported in LR or PSE 9.

As mentioned previously, I understand that muted colors occur when looking at images in an application that is not Color Management Aware, but why does eveyone else's photos appear fine on this forum when I look at them in IE?

Because you've never seen them look any other way.

Muted colors should only occur when viewing a wider gamut image in a non-color managed application. Can you post the image here?

So have you addressed number 1 on your list?

Yes, used a Spyder and Pantone ColorPlus. It created an ICC profile that my Dell UltraSharp monitor uses.
