I have enabled the option for tab queuing in Firefox for Android, according to this [[Open links in the background for later viewing with Firefox for Android|article]] . Therefore, when I open a link from outside of Firefox, the notification panel at the bottom of the screen appears, and it immediately opens the link in Firefox if I click on ''Open now'. However, if I decide not to open it immediately and click other links to be queued, the app notification with ''tab waiting'' (as shown in step 4 from the above article) does not show up. The phone is a Xiaomi Mi 9 Lite (Android 10), Firefox for Android version 68.8.1. I have already enabled all notification options in the app settings and I have disabled all battery saving options from Xiaomi settings. Thanks!
