The tabbed browsing changes from bug 308396 put a close button on each tab. In trunk win32 cairo builds, the background close icons are not showing up. The culprit is a css rule setting opacity: 0.7 on them here: http://lxr.mozilla.org/mozilla/source/toolkit/themes/winstripe/global/browser.css#116 Overriding this to opacity 1.0 in userChrome.css fixes the problem.

Created attachment 209703 [details] Simplified testcase It would appear that opacity is broken in general.
Summary: background tab close buttons not showing up in Firefox → opacity doesn't work (background tab close buttons not showing up)

I see broken opacity in Camino and Firefox on OS X (both trunk) also. Hardware/OS -> All/All
OS: Windows XP → All
Hardware: PC → All
