Deleting a scroll bar with firefox in a module produced with storyline 360

Hi Mounir,

Thanks for sharing that screenshot of what you're experiencing! It looks like these are normal browser scrollbars that are enabled when the course is larger than the browser window.

I recommend looking at the option to adjust your browser size in the player. This user guide shares more.

There are also a few discussion on the Mozilla support site on removing or reducing the size of the scrollbars. Take a look here and reach out to them if this is something you'd like to try!
