I am creating a Firefox Web Extension (and not adding an old style). My application has a manifest.json file and I installed the icons:
"icons": { "16": "data/icons/icon-16.png", "24": "data/icons/icon-24.png", "48": "data/icons/icon-48.png", "64": "data/icons/icon-64.png", "96": "data/icons/icon-96.png", "128": "data/icons/icon-128.png" },
However, the icon still shows the default plugin icon on the add-ons page:

The icon displays correctly in the Firefox Add-on Manager. I also tried putting the icon.png file and icon@2x.png in the root directory of my addon, but no luck.
I have an old addon that shows right above my new addon that has a custom icon, so I assume this is possible. Does anyone know how?
