Upgrade to Ubuntu 10.10 leaves some pictures in Firefox with a strange green hue

Version of Firefox is 3.6.15. After an upgrade, some, but not all, pictures have a greenish color to them. We're talking things like jpg, not flash or anything like that.

Fix:

In the Firefox address bar, type:
about:config

Yeah, yeah, you'll be careful. Set:
gfx.color_management.mode

to 0 (zero, if you can't decide whether that's "oh" or "zero"). My setting that had not been working was 2.
