As mentioned in other threads, great script!

I cannot rate it unless I create a new thread so ... well ... here I am.
Love it!

Thanks @mikedl

You had cameo appearance there

You can modify the script and change it, for example, like this

GM_addStyle("@keyframes slideInRight {\
  from {\
    transform: translateX(2000px);\
  }\
  to {\
    transform: translateX(0);\
  }\
}\
@keyframes slideOutLeft {\
  from {\
    transform: translateX(0);\
  }\
  to {\
    transform: translateX(-2000px);\
  }\
}\
html {\
  animation-name: slideInRight;\
  animation-duration: 1s;\
}\
.kthxbye {\
  animation-name: slideOutLeft;\
  animation-fill-mode: forwards;\
}")

addEventListener("beforeunload", function() {
  document.documentElement.classList.add("kthxbye");
})
