STEPS TO REPRODUCE
1. Enable the Plasma browser integration add-on on Firefox.
2. Start downloading an AppImage program, e.g. https://github.com/balena-io/etcher/releases/download/v1.18.11/balenaEtcher-1.18.11-x64.AppImage
3. After the download is finished, there will be a notification on bottom right (first attachment), click on the "Open" button there.

OBSERVED RESULT
Nothing happens i.e. the user can't open the downloaded AppImage.

EXPECTED RESULT
These Dolphin prompts should appear:
1) "What do you wish to do with this file? Execute/Cancel" (second attachment) 
2) "Warning: This will start the program: [...]; If you do not trust this program, click Cancel" (third attachment)

Does it work if you open the downloaded file from the file manager, rather than the "Open" button in the notification?

If so, I suspect this is an issue with plasma-browser-integration not have the "allow executing code" bit set on its open job, which is probably intentional for security reasons, but maybe should be relaxed for this specific case to not break it.

Yes, the second and third attachments are from opening the AppImage using Dolphin.

Thanks. Then what I suggested is probably the problem here.
