The opacity and background-color: transparent css styles are apparently ignored. (I will make an attachment for this in a bit) Reproducible: Always Steps to Reproduce: 1. Install the test extension on a Linux machine 2. Click on Panel Test -> Open Panel 3. A xul panel appears Actual Results: The xul panel appears and is not transparent Expected Results: The xul panel appears and is transparent This happens for me on Linux; doesn't happen for me on Windows and OSX. I notice the Ubiquity extension uses a XUL panel but doesn't offer transparencies in Linux. Installing Ubiquity on a Windows or OSX machine offers transparencies for the panel.
Created attachment 431293 [details] An extension that opens up a xul panel and tries to be transparent. Please ignore the name of the extension. This is just a test extension that shows transparencies on OSX and Windows but not Linux.

The Inspector (landed in 3.7a+) uses a panel with transparency for its highlighter. This is going to block this or we'll need to come up with an alternative for linux. cc'ing Enn.
