If I set the background of an element (for example a table cell) to #b9ba9f, Firefox in OS X shows #aaac8e instead (measured with ColorZilla and DigitalColor Meter). Haven't tested with other colors.
Doesn't happen in other browsers for Mac (tested on the same machine), nor in Windows (not even in Firefox - same release - for Win)

Reproducible: Always

Steps to Reproduce:
1. visit given URL with Firefox/OSX
2. measure colors with your prefered tool

Actual Results:  
Bug reproduced

Expected Results:  
It should show #b9ba9f, as specified

Actually I did test another color, as it is possible to see in the test page I posted (http://sbonzix.info/2009/06/color-trouble-firefox-os-x/)

What are your settings for 'gfx.color_management.mode' in 'about:config' ?
(2 is the default)

It was set on '1'. Switching it to '2' did the trick (now the colors show correctly). Thanks.
Does '2' mean 'false', i.e. no color management?

'1' means color management for both images and css/html colors. '2' means color management for images with embedded color profiles only.

Oh, OK.

I had color management turned on in version 3 (the key was 'gfx.color_management.enabled' and the possible values were 'true' or 'false').

Then, the upgrade to 3.5 various betas probably kept that setting and translated it to '2' for "gfx.color_management.mode".
Is that possible? Because I don't remember changing it.

Thanks.

Yes if you had the pref turned on in Fx 3, then that is the way it is converted.
I think.
