I recently had to go into the web-inspector and un-blur a website (I think Quora?)

I usually just press F12 and delete it with the DOM tree inspector.

Is "DOM Delete" automated?

I guess that's the one:

https://addons.mozilla.org/en-US/firefox/addon/dom-delete/

Yes, it seems to do basically that. So you can just click on stuff, and it's gone.

I just add them all to my adblocker list. Right click, block element.
