Adobe firefly is not working, when I type the prompt and want the image to be generated, it just stays on a white screen, it does nothing.

Thanks for the update @SašaBP 
After reviewing the recording you shared, it looks like the initial URL being used is the issue. Here’s the link to the Firefly webpage, this should allow you to access all other features just fine. 

If you run into a similar issue again, please let us know.
