Firefox Scrolling, Click to continue does not appear

Really sorry you're hitting this roadblock in Firefox, Felix. Happy to help!

To start, can I confirm if you're referring to the next button that appears at the bottom of each lesson?

If that's right, I'm having a little trouble recreating both behaviors in a test Rise course–here's the sample project and here's a quick peek of what I saw in Firefox.

Have no fear though, as we'll help you get to the bottom of this! A few more questions:

• Did you export the project for LMS or Web distribution, or are you using the Share link?
• Is this happening on multiple browsers or only Firefox?
• Mind sharing a link to your Rise course here, so we can take a look? We'll give it a test and let you know what we find!

It is also happening in one of my couses (made with rise). Not only the Continue-Button is misssing. Several pictures and interactions don't appear - there ist empty space. 

It works in Chrome.

Hi Stefan! Would you mind if we took a closer look at your course? If that works for you, please open a case here and include the course Share link. We'll test it in Firefox and let you know what we find! 

Hi 

We happen to face the same issue, With what research I have done , it has something to do with the communication speed between Firefox and rise when published within an LMS. Web version works correctly. can you please assist
