    Transparent background with Firefox addon panels

    Hello,

    I have a new computer with Windows 7 and Ubuntu 12.04 installed.

    My problem is as follow:

    Firefox Addon panels do not have a background at Ubuntu. The same Addon panel is correctly displayed at Windows 7.

    The panel is created by a Firefox Addon. The Addon is: https://addons.mozilla.org/de/firefo...arch-optimizer

    My configuration:

    DISTRIB_ID=Ubuntu
    DISTRIB_RELEASE=12.04
    DISTRIB_CODENAME=precise
    DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS"

    AMD RADEON HD 6450
    Beschreibung: VGA compatible controller
    Produkt: Caicos [Radeon HD 6450]
    Hersteller: Hynix Semiconductor (Hyundai Electronics)
    Physische ID: 0
    Bus-Informationen: pci@0000:01:00.0
    Version: 00
    Breite: 64 bits
    Uhr: 33MHz
    Fähigkeiten: pm pciexpress msi vga_controller bus_master cap_list rom
    Konfiguration: driver=fglrx_pci latency=0

    Firefox: 14.01

    I attached two screenshots. The Windows screenshot displays the panel with the correct background. The Ubuntu screenshot shows the missing background of the panel.
    I added the xorg.conf, too.

    I installed the fglrx driver via "System preferences" -> "Proprietary driver"

    I would be thankful for some ideas.

    Best regards,
    Andre

    Re: Transparent background with Firefox addon panels

    I made some progress and it seems that error is in the firefox addon panel object.

    I have the following definiton in my lib/main.js file:

    Code:
    var wsoPanel = require("panel").Panel({
      width: 350,
      height: 500,
      contentURL: data.url("myHTML.html"),
      contentScriptFile: data.url("myJS.js")
    });
    When I set the "width" and "height" propertites, the background of the panel is transparent. When I delete these two properties, the background has the color defined in the CSS of the myHTML.html file.

    Any ideas why that happened?

    thank,
    Andre
