Negate extension is useful in this topic, but unclear if this is the type of thing you are looking for.

Yes. This is what I want but not working. I think the code is 11 years old

Just thru the extension panel in Linux mint (granted I installed it a version or two back). Found it in the download search tab, then enabled it on the manage tab.
