Firefox "Add to Homescreen" or Auto App Shortcut only working after reboot

Hi,

i have a problem and would like to ask if other people experience the same.

If i use in Firefox the "Add to Homescreen" Setting to create a shortcut to a page on HomeScreen, the Homescreen opens but nothing happens.

After a phone reboot these icons suddenly appeared.

I also noticed the same behaviour with new installed Apps, which do not create a App Shortcut, but after an reboot they suddenly appeared.
