The userscript collection I wrote makes life easier and better. I use the browser extension TamperMonkey to run and manage userscripts. You need to install it first to use userscript.
Visit a list of some of my userscripts on the GreasyFork website here.
Each folder in the scripts folder contains a script.user.js file, which contains the script code. Click on that file, then click Raw button to install it.
