Fire tab asverts

I’ve been using a fire tab for my dashboard for a couple years with no real issues, in the past week or so I’m constantly getting adverts show up, and the screen locking. I’ve not had this in the whole time I’ve been using it, has something changed that I need to change to stop this happening?

I haven’t seen those issues, but it does seem like over the years it has fluctuated from lots of restarts/adverts over a month’s time, to no restart or interuption for weeks. One of mine shows OS7.3.2.9 release as of Dec 18th right now. I don’t normally manually update them, but I think they force auto-update after enough time elapses.
