Bypass paywalls for scientific documents by downloading them from sci-hub instead of paying something like 50 bucks for each paper. This script adds download buttons on Google Scholar, Scopus and Web Of Science, which lead to sci-hub.tw. In this way you can get free access to scientific papers even if you (or your university) can't afford their prices.
I'm not using (and thus developing) this script as much as I did before. If you find it's not working anymore, consider using Sci-hub button: it also works on many more sites than my script!
