Reproducible: Always Steps to Reproduce: 1. Override page colors (Tools->Options->Content->Color). Check "Use System Colors" and uncheck "Allow pages to choose their own colors". 2. Load the attached "disabled.html" or load any page that has disabled form controls. Actual Results: The left set of controls in the "disabled.html" are active controls and the right set are disabled controls. Notice that the radio button and checkbox maintain their disabled colorings, however the button and text box are difficult or impossible to identify which is the disabled form control.
Is it a problem for XUL as well?
No, Aaron. It appears not to affect the XUL equivalent controls. I'll attach an XUL equivalent to the HTML version.
Created attachment 264007 [details] XUL version of the HTML controls in the previous attachment. This is an XUL version of the HTML controls in attachment 262766 [details].
Fixed on trunk a while ago.
