Greasy Fork镜像

for some reason i don't get the popup when i go on geoguessr. i've tried refreshing, still not working. also i don't understand how to get the "user id" because i don't see it anywhere.. i'd appreciate the help! i can enter the website linked but as stated idk the user id

IF the script is installed, it should open automatically.

Press F9, do you see a popup?

If not then its not installed correctly.
