Hi! I’m creating an SVG document that is getting served up through the new filterResponseData in my background JS script. Inside the SVG document I’m trying to use a blob URL (e.g. “blob:moz-extension://”) as an image source but it is not working. I don’t believe that it is a CSP issue as I turn off CSP and I still don’t see the image, nor do I get any CSP warnings like I usually would. In theory I could probably Base64 encode the images too but it seems unnecessary.
For what it’s worth, I also have a strong reference to the blob someplace so I don’t think that’s a problem.
Is this use case supported? I understand it’s a probably a bit arcane. Thanks for any help.
