As the title states, I have been testing out web push with a project I have in mind and am running into the issue that on firefox after making a request to send a web push, it takes a few minutes before firefox acknowledges that it got it and shows it. Afterwards, web pushes are shown instantly until again after being inactive for some time (not really know to me) it is delayed again in receiving web pushes. On chrome, they are received instantly every time. I am also setting the priority to the highest when making the push request.
