Firefox default theme not working on high contrast
When FF23 upgraded to FF24 the default theme was broken
I usually have white text on black background set for Win8 high contrast theme. It worked fine in FF23
Now the default theme in FF24 is white with white text and the toolbar buttons have black surrounds on white toolbars. The sidebar is unreadable. The toolbar buttons themeselves are OK displaying as pale icons on black.
I have tried to fix by ticking use system colours - no change. Unticked no change.
Safe mode - no change.
Unticked/ticked harware accellaration - no change
I have tried re-installing, plus upgrading for FF25 beta then backdown to FF24.
Hope you can help.
As soon as you change the default background color from white (or light grayish) to black then always problems can arise.
This happens when you change the default colors in Firefox for web pages or use an inverted high contrast theme for the user interface and possibly web pages (don't know if this effects the appearance of web pages).
In the case of this thread it happens in the Firefox user interface.
Changing colors in Firefox only effects the appearance on web pages and usually only shows when the web page specifies only the text color and assumes that you still have a default white background (which of course they shouldn't), so you can get a wrong contrast combination (possibly back text on a black background).
You would probably need to use a full (complete) theme that is compatible with an inverted (white text on black background) theme to make this work properly for the user interface. I wouldn't expect things to work properly soon (or even later) in a next Firefox version.
