By the way:
- Firefox is as indie as your favorite popstar
- This pop-in is both based on a dark pattern and has no way to say "No/never", only "not now"
- Remember when people chose Firefox to avoid popups? I've constantly been getting the opposite these last few years (and no I won't take the ages to fix every little thing in about:config like if it would be disabling the anti-features of Windows 10)
