Does this script work for you? I installed in FF and tried on 3 sample links and none of them produced the extra link :/ Icon in Greasemonkey shows that scripts recognized URL and was running on each site

Yeah I've been using it for at least 6 months and it's been great. Running on Chrome w/Violetmonkey.

As an example I get the icon in the top left of the page for this random IEEE paper: https://ieeexplore.ieee.org/document/6025669
