Disabled checkboxes however appear the same color as enabled checkboxes. The result is that in high contrast mode, you can't tell the difference between a disabled checkbox and an enabled checkbox. Reproducible: Always Steps to Reproduce: 1. Enable high contrast mode 2. View a page with disabled and enabled checkboxes Actual Results: Checkboxes appear the same. Expected Results: Disabled checkboxes should be distinguished from enabled checkboxes.

Using Windows 7 (Maybe others) High Contrast Mode breaks a lot of images on the internet. Bing.com - the main picture image does not load. Google Gmail - all the menu icons have a line through the middle. Also, when trying to compose a new email, all of the editing icons like: BOLD, ITALICS, .... ALIGN CENTER, ALIGN RIGHT are all invisible. One does not have to use high contrast to make the bug happen. Just set Firefox Menu -> TOOLS -> OPTIONS -> CONTENT TAB -> COLORS BUTTON UNCHECK THE BOX: ALLOW PAGES TO CHOOSE THEIR OWN COLOR Try going to Bing.com - the image is also gone as with High Contrast mode. Unfortunately, a High Contrast Windows Theme is not really usable with Firefox because of all the missing/invisible content.

I don't understand comment 4. Even after Just set Firefox Menu -> TOOLS -> OPTIONS -> CONTENT TAB -> COLORS BUTTON UNCHECK THE BOX: ALLOW PAGES TO CHOOSE THEIR OWN COLOR there is no visual difference between an enabled and disabled control in FF16 using High Contrast #1 in windows 7

I suppose we're actually using native widget rendering here...
