Firefox notifications showing a lot of blank spaces

Hi, I noticed lately that notifications shown in Firefox is showing a lot more blank spaces.

These aren't happening in Chrome though. Currently using Firefox Version 113.0.1. Also to note is that I am not using native Windows alerts/notifications. I disabled that using alerts.useSystemBackend = false in about:config.


  • Most likely the issue is related to those flags, try resetting them to see.

  • So using Firefox's notifications is not supported anymore?

  • You can try changing the extension notification options between text or rich notifications and see if that makes a difference, otherwise the notification updates are managed by the browser.
