I created an e-learning course and published it to web. On several slides in this course in Firefox browser (91.0.2 v.) some pictures disappear and appear randomly after some time (for example 30s). These errors do not occur in Chromium based browsers - like Microsoft Edge. These images disappear/appear when the window of Firefox is rescaling too. The problem has been reported to authoring tool support and has been confirmed by them. Any suggestions from Firefox browser users?

Make sure you are not blocking content.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
