[webextension] Disable `background-image`

[ffoodd]

Wouldn't it be valuable?

This would help us see if any useful content is missing when disabling backgrounds…

What about testing if computed style for an element has a background colour? I kind of remember a reference about it that says that if you add a background image, you should also add a background colour.

Basically it's very hard to programmatically diagnose what the real background is (e.g. an element over another element but whose parent is collapsed because the element floats for instance: I'm not sure you can easily find out on which background the font is).

Or you meant: for a visual checkup? If so, yes, good and simple idea to implement (I guess)

My idea was indeed for a visual checkup!

But ideas are just seeds, meant to grow up ;)

I vote for: simple. ;)
