The browser window in FF does not appear to honor Windows High Contrast
Mode? Am I doing something wrong or do I need to install a plug in like I
do with Chrome to make this work?

Thanks

Yes,

The browser controls are all displayed in high contrast but the setting has
no effect on the display of the page. I have tried multiple sites just to
be sure. Chrome prompted me to install a plug-in but it worked, sort of it
gives you its own high contrast theme that you have to configure to match
what you have in windows but I seems to have some good flexibility. Perhaps
FF requires a separately installed plug-in too.

Well I just answered my own question. You can get high contrast by setting
the colors using the no squint plug-in - and you can keep the background
images which are lost with IE in high contrast.

Interestingly Adobe Reader does the same thing with documents - the
controls for reader are displayed in high contrast and the displayed
document is left the same as the original. More fodder for the folks who
find PDF accessibility less than sufficient. And more fuel for me to
continue insist that we publish all of our critical program information in
HTML.

Michael, this statement isn't exactly accurate. Reader gives the user choices. In the preferences for Reader and Acrobat you can choose how reader responds to high-contrast mode. If you select "replace document colors" you can set it to match the Windows color scheme, or you can choose a different color combination. If you choose the windows color scheme and then set the windows high contrast setting, you'll notice a difference in the PDF document content also.

For that matter, in Firefox there is a setting in the "content" tab that allows you to adjust the colors for the content, and there is a checkbox that reads "use system colors". When checked you set the experience that I think you are probably expecting.

Hope this helps,

Thank you Andrew,

As usual you are the source of all things wise and wonderful and after 10
years I am still learning from you.

Everything worked as expected with PDF documents but I now I am getting
some strangeness with our LiveCycle forms. The form field areas are
inheriting the windows text color but not the background color for the
information entered. The form text is left as it was in the document. Are
we doing something wrong in our development process that is defeating the
foreground and background color inheritance. If you would like I can send
you a form off line.

Mike

Whoa! They say that flattery will get you nowhere, but that line is actually strangely effective.... :)

The form field areas are inheriting the windows text color but not the background color for the information entered. The form text is left as it was in the document. Are we doing something wrong in our development process that is defeating the foreground and background color inheritance. If you would like I can send you a form off line.

Ok, so here's the deal. The high-contrast tool in Reader has a limitation, and that is it changes the text color and the primary page background color only. There's so much going on in a PDF document that developing a heuristic to determine what page objects are playing the role of background colored objects with text in front and similarly for text what the color of its background is. This is the same problem that Apple solved by just implementing an invert option and Windows solved by removing many background areas in high contrast mode. So it isn't a great solution and I'm talking with the team about it. What happens is that when you create a page and add a black background to the page and use white text, the high contrast feature makes the white primary page background black (or whatever color you've set), the text from white to black (again, based on settings) and the black background doesn't change. The result is black text on a black background. Ugh.

You can hit select all on your document to see if you get the same result - the text will appear when selected (no, I'm not suggesting user select text as a solution).

Thank you again Andrew,

We had set background fill to white on all of the form field objects.
Removing the fill fixed the problem. Now just to remove fill on 400 forms...

Michael,
I just checked again and High Contrast Mode works fine on FF 24 ESR
However it is broken on my FF 31 Instance.

What version are you using?

Is anyone aware of a bug being logged for this? If not I'll log one when I
get a chance.

Regards,
James

Maybe the following bug is the same one:
