Get rid of the tooltip in contour plots

When I plot a curve using ContourPlot, and then move the cursor near the plotted line, a pop-up window (tooltip) with the corresponding function formula appears.

Very often I find it distracting, especially when the pop-up window is large and I want to get the coordinates.

How can I disable this?

In ContourPlot, ContourLabels -> None.
• @Agnieszka Try replacing Tooltip with (#&) in the output (see ReplaceAll). – Szabolcs Sep 5 '17 at 8:48
• Did you look up ReplaceAll? plot /. Tooltip -> (#&). – Szabolcs Sep 5 '17 at 8:53
