I am using Firefox 68.4
as a client for chat (Mattermost). When a message is received, a short notification popup appears. It only stays for few seconds and then disappears.
Where is this timeout configured ? How can I change it ?
Ideally, I would like the popup to stay until I click with my mouse. If that is not possible, at least I would like to increase the timeout.
How can I do this ?
Also, I would like to define a sound notification, whenever popup appears.
UPDATE
I am using plain Openbox
, without any other desktop environment. I am not aware that I have any notification daemon. I am almost sure, the notifications are handled by Firefox
. The pop-up window looks like Firefox
.
