I have not run firefox (win7) for a while and it wanted to update so I let it. Now I have lost the colormangement I need for my wide gamet monitor used to work


The config info look to be unchanged, pointing to my version 2 icc profile I built over a year ago that was working fine until the auto update.

But since the update the monitor profile is not used, and naturally reds are awful on the wide gamet monitor.

What might have changed during the update from the old firefox version (don't know what version, maybe a year and a half old).

It's possible that a default preference was changed. You might check out the following:
