It seems that the newer version of the smartermail webmail (at least Build 8629) are showing a yellow "Browser notifications have been disabled in this browser" popup when you login and the browser notifications are disabled. People who disable notifications do it on purpose to not be disturbed by popups, so it doesn't really make sense to nag this population with a popup telling them that they are missing out on more popups. It also seems that the acknowledgement of that popup must be stored in a cookie which gets cleared when the browser closes (at least the way my browser is set up), so I get the popup again every time I open the browser. 

Is there any way to disable this popup for the whole server? Or at least to store the acknowledgement server side so you don't bug the users every time?
