Don't fuck with copy too, my schools e-textbook thing won't let you copy text when quoting it for an essay.
Edit: I appreciate the help but this is on a school laptop, we can't install anything nor open inspect element. Also I already found a workaround by cntrl+c-ing before I lift the left click and it goes to highlight mode.
I always just find a pdf to use even if I had to pay for the service. One time the pictures they provided (tables) were so difficult to read that I tracked down the original source material and sent copies to the professor and the rest of the class.
