Re: Which reminds me...
On new browser windows, when Options / General / Home page is set to default of "Mozilla Firefox Start Page" then the content below the search text control is things like "Top Sites" (your recent most visited links) and "Recommended by Pocket" , links to charming articles like "Why the scientific finding that trees 'sleep' at night is beautiful" and "The Perks of a Play-in-the-Mud Educational Philosophy".
(The above described as on FF59.0.2)
If the mooted "horrors!" are as unobtrusive and ignorable as these suggested links on an otherwise blank startup page, then this is much ado about nothing.
