Unable to download blob images with downloads API

[bumbaras]

it's more feature request than issue.
Such site is using images coded as blob (or whatever blob object is)

Of course addon is not detecting images in it. Is is possible to add the way to fetch images from such mechanism?
Firefox is also not able to detect or save images, but browser capabilities are limited on this field.

The addon is able to detect the image URL, but then the download fails.

However, we need a way to make fetch work on page script blob.

In general I would suggest to not count for FF team too much. FF is no longer so user swayed into browser.
The team has own ideas and taking also into account if user should be download or not something. In my opinion Chrome is less strict in this matter. I have seen sites where Chrome was able to download complete webpage as complete, where FF wasn't.
It doesn't mean Google will provide additional download feature if current is not working, and Chrome is also not able to download blob images.
