Firefox Quantum also nags constantly about logging in and syncing devices, not that I'm against it, it's great when you have multiple devices and don't want to install the same plugins, sync bookmarks, etc.
That's well and good but I'm replying to the comment above me which stated:
> I certainly don't appreciate that Chrome wants me to log in every time I use the browser (and getting more and more insistent at that lately from what I hear)
Did you have to disable the requests? Or are you really saying that on a virgin installation, Firefox never tried to get you to login and sync? Are you on Apple/Linux? I was able to disable most of the reminders to sync on both Android and Windows but I eventually gave in, in order to sync all my plugins and bookmarks.
