FireFox delaying animation video in the Articulate course

Oct 20, 2022

I've been trying to figure out why all of a sudden my courses are not working correctly in Firefox when I didn't have this issue before. I have animation videos in my courses and when I run it in Chrome no issues at all they are extremely short, small animation videos. When I run the the Web or LMS version of the course in Firefox it "freezes" or if "its loading" it sits there until the full video is downloaded before it starts playing. This is a huge issue because the client wants to be able to view the course in any browser the student chooses. Chrome and Edge aren't giving me the same issue FireFox is is there a way to fix this problem. Is it Articulate or is it the Firefox Browser? Anyone have any advice.

Hi Kelly, have you been able to open up the browser console in Firefox to see if anything unusual is happening with downloading files (CTL+SHIFT+I and select the Network tab) or any JavaScript errors (CTL+SHIFT+J).

It does sound very unusual that it would be working fine in Chrome and Edge, but slowing down in Firefox. Hopefully the Network tab and JavaScript console will reveal something different is happening between the Chrome/Edge and Firefox.

Hi Kelly, 

I'd like to ask a few questions to help clarify your experience: 

  • Do you have the latest version of Firefox installed? 
  • Have you tried using Firefox's private window to see if this improves how animates are displayed?
  • Do you have any browser extensions installed? If so, have you tried turning them off one at a time? 

Additionally, would you be willing to share a copy of a project file that has animations here or in private by opening a support case so we check the issue? We'll delete it afterwards!

Its the latest Browser, and I tried your suggestion with the private window it didn't make a difference. No extensions install. The company controls what's placed on our computer and I usually can't change much of the settings. Unfortunately, I'm not allowed to send you the course.
