I have no idea how to restore my start page with 4 rows of "icons" . Personally managed without interference. Would like that back. Where do I go to set that up again or RESTORE it . I can't believe this has been destroyed. Very Disturbing.

Firefox apparently just "upgraded".

So I did find "SETTINGS"; Found "New Tab" from there. Set up icons were still on the page although very jumbled. RE-setting up just now. You can do it.
