Before I can even get on my computer, I can see Notifications for Firefox. I use my password to login to my desktop computer and the Notification in the upper right hand corner are there for a few seconds more, then they disappear. I do NOT know where to see them again and I truly would like for this activity to stop. Where do I find Notifications after I launch Firefox (my preferred browser and the ONLY browser I use) to see what the notifications have to say, and how can I disable Notifications?
