1109395 - No data: urls for W3C Notifications icon property

Status: NEW

(Firefox :: General, defect)

Description

[Jonathan Protzenko [:protz]]

It seems like data: urls don't work for the icon property of W3C Notifications. I'm no expert in spec reading, but http://www.w3.org/TR/notifications/#concept-notification doesn't seem to forbid this, does it?

STR: launch using the console, for a page that has been granted notification permissions already:

new Notification("blah", { body: "body", tag: "tag", icon: "data:image/svg+xml;base64,PHN2ZyBjbGFzcz0nc3ZnIHN2Zy1pY29uLScgdmlld0JveD0nMCAwIDEwMCAxMDAnIHByZXNlcnZlQXNwZWN0UmF0aW89J3hNaW5ZTWluJyB4bWxucz0naHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmcnPjxjaXJjbGUgZmlsbD0nd2hpdGUnIHN0cm9rZS13aWR0aD0nNScgc3Ryb2tlPScjRkRFRTAwJyByPScyMC41JyBjeD0nMjUnIGN5PScyNScvPjxjaXJjbGUgZmlsbD0nI0ZGMDBGRicgcj0nMjMnIGN4PScyNScgY3k9Jzc1Jy8+PGNpcmNsZSBmaWxsPScjOTBFRTkwJyByPScyMycgY3g9Jzc1JyBjeT0nMjUnLz48Y2lyY2xlIGZpbGw9JyMwMDgwODAnIHI9JzIzJyBjeD0nNzUnIGN5PSc3NScvPjwvc3ZnPg=="})

The data-url is valid (it displays fine in the URL bar) but doesn't seem to work in this context.

Thanks,

There's nothing in the DOM implementation that would make this not work, at first glance.  Presumably the UI is doing a security check that forbids data: URIs here, though.

I've noticed that notifications don't work with icons with dimensions != 32x32 pixels. Have you tried resizing your image?

For example here (https://github.com/andreasgal/j2me.js/pull/579/files), I've had to resize the image before being able to use it (and I'm using it via a data URL).

It's an svg, and I just tried setting the viewBox to 32x32, but that didn't help.

So I guess I should probably rename this bug to "data: urls for W3C Web Notifications only work for non-vector, 32x32 images"?
