Firefox addon - how to listen to a text highlight event on a web page

Question

I am writing an addon that needs to be done in order to capture the time when someone highlighted some text on a web page. Is there any way to listen to this event?

Thanks Kapil

Answer 1

There is no special event for this. But you can listen to the mouseup event and check the selection returned by window.getSelection() not empty and / or different from the previous selection.

Answer 2

You can add a listener. The Source window (viewSource.js) does this so that it can update the row and column number.
