Problems with zoom in Firefox

Jürgen 2 years ago updated by Vitaly Ovchinnikov 2 years ago 4

In Firefox zoom will not work correctly, if you zoom in or out the complete scene will disappear. But strange if you embed the exported Koru html file in an iframe it will work... Here you can test it:

The original html file:

The file embedded in an iframe:


Using https or http makes no difference. In all other tested browsers (Chrome, Opera, Edge and the f******** Internet Explorer) it works perfect, only in Firefox it doesn't.

Hello Jürgen,

I've just made a quick test in both Firefox and Firefox Nightly and both zoom just fine. What is the Firefox version you use and what is the platform?

Also, I would recommend to use "Export for server" if you want faster and more interactive loading of Koru scenes online. Use single-file export for offline purposes only.


Windows 10 Home 1803 64-bit, Firefox Quantum 67.0.4 64-Bit

We love the single files for distributon and creating previews for our customers, but we will test the server export on monday and will check if it has any effects. We have similiar installations on different systems and some get the same trouble, e.g. Android Marshmallow and Firefox or Firefox Beta, Windows 9 and Firefox. We will go in a deeper check by disabling installed add-ons and will post the result. But this will last some time...

Best regards,

BTW: It would be nice if other users can check the links and post the results with os and browser information

Ok, found it out: Logitech SetPoint Addon for Firefox causes the problem.

Best regards,
