I am using version 147.0.1 (don't know when last update) For the last 1.5 hrs I have been trying to restore the extensions icons as well as other, to the tool bar. when I close "customize" after putting them there they disappear, as does the "puzzle" piece I put up there. What is going on? I have read numerous articles on how to fix this to no avail. Only one character will stay to the right of the added search bar.
