User Script Managers
A userscript manager is the browser extension that injects scripts into websites
to change their behavior to your liking.
Recommendation
All scripts on this site have been developed and tested with Tampermonkey on firefox.
Try other browsers and other script managers at your own risk.
No script should use firefox or chrome specific features,
which means they should also work in other modern browsers.
If you prefer, you can use greasemonkey.
Get Tampermonkey,
Get Greasemonkey (Firefox only)
