Can't remove buttons in toolbar

[aaJoe]

Is there a trick to this in 8.51?  Before I just right clicked, then 
clicked "Remove from toolbar" and they were gone forever.  Now, every 
time I open the browser my Address Bar is filled with these pointless 
buttons for people with Alzheimer's who can't remember commands they've 
done thousands of times before. I even closed the browser first but they 
were there when I reopened it.  In Preferences I removed them again to 
no avail.
