Mouse "Snap to" Dialog/Dialogue Box not working in Firefox/Windows 10
Windows 10/Control Panel/Mouse has a system feature that will snap the mouse cursor to the dafault box in any dialog/dialogue box, so for example if you right click an image, and "Save to" the cursor will snap immediately to "Save" in the Win 10 dialog box.
For me this working fine until yesterday and has suddenly stopped working. Other browsers respect the Win 10 settings so it is something in firefox that is overriding Windows.
Can't see any obvious settings in about:config
Would be grateful for any help
[I have refreshed Firefox and am ready to do a complete re-install if necessary]
