this is based on another script i found and i just added more options, and 2 years ago i knew almost nothing about coding, man, i'm proud it got so popular tho, maybe not that i know a bit more i will see what i can do. i was 14 when i posted it.
Broken
It does not work for me. I think it is that Greasy Fork changed its' URL scheme and this script needs updating.
I'm on Windows 10, Firefox 57.0.1 64-bit. I have tried it on Tampermonkey 4.5.5633 and Greasemonkey 4.0.
