Contrary to popular belief, Safari is not the only browser to support ICC colour profiles........
I’ve discovered that Firefox can be set up to enable colour management profiles. To do this, in the address bar type
about
:config
You will be presented with a long list of preferences. You need to add a new preference called “gfx.color_management.enabled”
To add this new preference, right-click anywhere and choose New, then select the type of preference as
Boolean
You will be prompted for the preference name, enter the text
gfx.color_management.enabled
and set the initial value to
True
Close Firefox and then reopen, your browser will now use any colour profiles embedded in images that are displayed.
To reset a preference to its default value or to remove an added preference, right-click on the preference and select Reset. If you added the entry via about
:config, the preference will no longer be listed after restarting the program.
