Would it be feasible to implement JavaScript so that when hovering over or clicking on a word on a webpage, the word can be captured in a variable? I am interested in creating a Firefox extension with this functionality.

There is no actual function for clicking a word since it is not considered an object. However, you can still highlight a word and retrieve its value. Here is an example:
https://developer.mozilla.org/en-US/docs/Web/API/Window.getSelection
function bar() {
var selection = window.getSelection();
alert(selection);
var selectedRange = selection.getRangeAt(0);
// perform actions with the range
}
