HTML output from last Storyline 3.8 update laggy on firefox



When I generate my project with Storyline 3.8.20838.0 version (update released this month), all animations are laggy (very slow fps) in Firefox.

I tried to generate the same .story file with the previous 3.6 version with no issue. I think there is a bug in the last release. The HTML5 output is not optimized for firefox. Does anybody have the same problem?


Thank you

Hi, Olivier. I haven't seen reports of lag with Storyline 3/Firefox, so I'm glad you reached out!

Can I grab a few more details?

  • What version of Firefox are you using? Also, is this happening on other browsers as well or just Firefox?
  • Is the course hosted on a web server or a learning management system?
  • If you can share a sample project with us for testing, that would be gold. We'll delete it after troubleshooting in a similar environment. If that works for you, send it along by using this private upload link!
