3D Printer Error with Duet WiFi, Firefox and JavaScript

[Gina]

I know there are others here using the excellent Duet WiFi control board and probably Firefox to control it.  Since a recent upgrade of Firefox I am getting a JavaScript error when trying to show the "Auto Bed Compensation" results.  Screenshot below.  Anyone know what I can do to stop this error and show the bed levelling results, please?

Might be worth putting that on the Duet forum. It's not one I have seen before. What version of DWC do you have. The latest stable version is 3.1.1 with 3.2 out soon. If you are still on 2.x it might be worth considering the upgrade to v3.

Made a mistake - should have said Mesh Grid Compensation and "Show Mesh Grid Heightmap".  Is that makes any difference.
