A few months ago after an update to Firefox the window would open but be transparent with no controls visible. I tried the refresh Firefox option which worked but left other problems. A website has a medium blue header at the top with white fonts (links) on it, which still appear that way in Chrome and Opera, but since the refresh the header is black with black fonts in Firefox (which of course you can't see). There are also variations of this problem on some other other websites. The only way I can see links on those sites is to set color management to override 'always'. Is there any way to fix this problem? Thanks Mike
