Sometimes, upon opening the add-on after it has detected the presence of userscripts (as indicated by the badge count) available on a website (scripts that are actually available on Greasy Fork), the add-on clears the screen and displays a "No scripts found" message.

I am aware that an updated version of this userscript exists for the add-on. However, I prefer to continue using the Firefox version, as I am not fond of having a floating button on websites.
