Captivate Accessbility Keyboard Focus Issue in Firefox

[VeeraElearning]

Hello

I have created a simple simulation in Captivate 9 using screenshots.

I have created the accessibility keyboard focus (tab order) and published the output as HTML5.

The keyboard focus is working find in Chrome. But whereas in Firefox the keyboard focus area is out of place or enlarged.

Attached is the screenshot for reference.

Can you please help us to fix this issue in Firefox.

Thanks

Veera
