Bypass paywalls for scientific documents
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.
Avoid quarrelling with your friends because you didn't catch the right answer to all their questions (even if some are really stupid, like "Which mobile OS does John prefers: 1)Android 2)iOS"). This script makes the correct answer appear bold.
Indeed: separate sponsored jobs from search
Separate sponsored jobs from search making them appear yellow. Useful to distinguish those jobs you've not searched for, but are in the results just because they're sponsored.
Facebook Videos without login on mobile
Watch Facebook videos on m.facebook.com even if you are not logged in. This works for public videos that are visible from PCs from everyone but are locked on mobiles for users that are not logged in Facebook. This is a preliminary version and works by clicking on the post (not on the play button) by opening another tab in the browser with just the video.
