I stumbled over this while designing an extension's pref panel, but it occurs also on DOM Inspector's pref panel. Reproducible: Always Steps to Reproduce: 1. Open Preferences, Advanced, DOM Inspector 2. Deactivate "Blink selected element" 3. Click on the "Border Color" colorpicker Actual Results: The colorpicker opens, allowing to select another color (although it's 'disabled' attribute is set 'true'). Expected Results: Nothing happens.

Confirming with build 2003032808 and Windows XP SP1. Lowering severity to trivial since this is only a cosmetic problem.

Funnily this was fixed as bug 260335, which was filed one and a half year later than this one :-) The fix is in Moz1.8alpha5. Note: Porting the fix to firefox is bug 273287 *** This bug has been marked as a duplicate of 260335 ***
