Does this extension only inject JavaScript?
I have JavaScript disabled by default in Chromium. I also use uMatrix with rules:
* * * block
* * frame block
* * other block
* * script block
* * xhr block
and I enable per-site what I want.
On the test page I enabled JS and allowed ajax from Google APIs just to test and I saw "1" appearing in the extension icon. However on no other sites which I visit I see no effect whatsoever.
So is this extension supposed to have any effect only when JS is enabled and resources are injected through XHR? Or is it also supposed to store locally other resources like css or images (which would be relevant since requesting such resources from CDN's can also lead to tracking)?
