unlocks locked symbolab step-by-step instructions by overwriting XMLHttpRequest
当前为
This script overwrites the XMLHttpRequest object to intercept Symbolab's request to the solution server.
It replaces all step metadata to remove 'locked for premium users' attributes.
Installing this script will automatically unlock all "locked" steps, for more advanced topics e.g. calculus etc.

Symbolab has changed server policy. Now, results are -never- sent to the client if you are not logged in.
Easy fix — just sign in to a free Symbolab account and the script will work as usual.
