The newest firefox build available in the ubuntu repos was 3.5 RC2, so I downloaded 3.5.1 from mozilla.com and extracted it to a folder on my desktop.
Then I changed my firefox shortcuts from /usr/bin/firefox %u to /home/me/Desktop/firefox/firefox %u .
Since doing this, some images (both parts of the UI, and images on web pages) are being rendered in greyscale. All the images in web pages affected are PNGs, but not all PNGs are affected.
Steps to Reproduce:
1. Go to site linked as an example.
2. Look at the images.
The logo up in the top left (a PNG) is fine for me, but the screenshot (also showing the problem in action, in case your browser renders it fine) I posted is all in greyscale when viewed with 3.5.1 (it's fine in RC2, other browsers
Should the images with the correct colours.
Firefox is using the default theme.
Disabling plugins does not fix the issue.
My computer Ubuntu 9.04 with both GNOME and KDE installed (GNOME is the default desktop).
Do you refer to the cc-by-sa image - and the other logo in the bottom right?
This image is greyscale.
Also - the site indicates it's in private beta - and has no other images - other than the toolbar links - do you perhaps have a login to this site?
Can you show it on another site?
Does it work if you change gfx.color_management.mode from 2 to 0 in about:config ?
@Ian: Sorry I forgot, beta password is at the offical blog http://blog.stackoverflow.com/2009/07/super-user-semi-private-beta-begins/.
It's ewok.adventure (it's posted publicly officially, so there's no harm posting it here).
The image in the thread is what I referred to (which you will see if you type in ewok.adventure).
As for another site: The favicon for this site (bugzilla itself) is also being greyed out.

I've changed the setting, and restarted firefox, and it still looks the same.
Update: It appears last time I restarted firefox, it was still running on another desktop, so it wasn't a proper restart. Now (with the settings changed), it is appearing correctly.
Firefox3.5 does Color correction for images with a color profile by default.
This looks like an issue with your used color profile/X server.
