I have an opinion that neither browser, nor OS or something else should not interrupt a workflow with webpages or other parts of OS. Idk how the browser deals with updates on other OS, but on Windows it is literally begging of updates. It is bad because we are living in a world when any update can be frustrating, for example, I have an old FF instance on one of my laptops just for playing Flash content and I _really_ need no update there.
