• Greasemonkey plugin

1. Create a file called xxx.user.js - the xxx is unimportant, the .user.js is what denotes the file as a Greasemonkey script.
2. Copy and paste the script into that file
3. Navigate to wherever you created xxx.user.js, at this point, Greasemonkey will prompt you to install it.
