My Firefox theme

I made a Firefox theme that blends with the simple graphics of this site. You can either download the .xpi file or build it simply by zipping and changing some file extensions:

Manual building

In a folder of your choice, create the file manifest.json with the following content:

{
  "manifest_version": 2,
  "version": "1.0",
  "name": "4pi srad",
  "theme": {
    "images": {
      "additional_backgrounds": [
        "images/0.png"
      ]
    },
    "properties": {
      "additional_backgrounds_alignment": [
        "right top"
      ],
      "additional_backgrounds_tiling": [
        "repeat"
      ]
    },
    "colors": {
      "toolbar": "rgb(63, 50, 38)",
      "toolbar_text": "rgb(238, 238, 238)",
      "frame": "rgb(117, 57, 39)",
      "tab_background_text": "rgb(174, 158, 153)",
      "toolbar_field": "rgb(25, 18, 12)",
      "toolbar_field_text": "rgb(238, 238, 238)",
      "tab_line": "rgb(41, 228, 212)",
      "popup": "rgb(117, 57, 39)",
      "popup_text": "rgb(238, 238, 238)",
      "toolbar_field_border_focus": "rgb(235, 106, 46)",
      "tab_loading": "rgb(41, 228, 212)"
    }
  }
}

Then, create a subfolder named images and put this file inside (make sure it is saved as 0.png, or alternatively change its name in the manifest.json). If you zip the folder containing manifest.json and the images folder you obtain the theme file, that you can rename with a .xpi extension.
