bug 371053 landed a bunch of cocoa widget changes without checking callers in XUL and themes. I think we have a short list of things that changed.

"Highlight"/"HighlightText" color changes affecting Pinstripe: mozapps/extensions/extensions.css (has HighlightText, should be ok) mozapps/extensions/downloads/downloads.css (no HighlightText, bug 371485) global/datetimepicker.css (has HighlightText) global/plugins.css (has HighlightText) global/tree.css (.tree-input has Highlight on borders) global/dialog.css (dialogheader has Highlight as bgcolor, color is HighlightText) global/richlistbox.css (has HighlightText, but there's an "outline: 1px dotted Highlight" on selected and focused items). I have just looked at the css, but I think changes that affects selection background-color is an improvement if there's a corresponding color style (HighlightText or hard-coded white). I also don't think the border/outline styles matters. Effects of dialog.css is unclear to me (not sure where it's used).
