Sketchup web : Ctrl-z not working with FireFox


I am using sketchup web version with the Go licence.

When under Chrome, Ctrl-z works as an undo shortcut.

But when using sketchup in FireFox, Ctrl-z does nothing. However, I see that k still works to activate/deactivate transparency.

I have experienced that under both Windows and Ubuntu.

I want to switch from Chrome to FireFox because Chrome sometimes hangs when working with sketchup. But I cannot work without ctrl-z.

Thanks for any help.

Did you check if the shortcut is assigned?

You could also try Alt + Backspace


Yes, undo is assigned to Ctrl-z

And Alt+Backspace does not work either.
