Screenshot of the issue
When downloading files with Firefox, a notification pops up informing you of the state of the transfer. There is a bar which should fill, but instead remains empty.
STEPS TO REPRODUCE
1. start a download on Firefox
2. let it progress
The bar in the notification is not updated, so it's stuck at empty.
The bar fills as the download progresses.
Linux: KDE neon Focal
