Hi I'm using Firefox on Windows 10. Normally within Firefox, pressing CTRL + left click opens a tab in a new background window. I'm left handed and use the mouse in my left hand. So I swap the left and right mouse buttons around within Windows settings, so the right mouse button is my primary button. I would then expect CTRL + right click to now open a tab in a new background window, but it doesn't. The CTRL is ignored. Does anyone know how I can configure Firefox so that the behaviour is consistent, whichever button is the primary one? Thanks.
