Problem: I had inadvertently removed my bookmark webpage star from my browser (Firefox v.70). I searched and couldn't find an answer as to how to get it back on my address bar. The closest answer involved clicking the "Page actions" (which looks like an ellipses; 3 dots) button which is adjacent to the bookmark webpage star button by default. Both were missing from my address bar. So I refreshed the browser and had to manually adjust all my settings again and reload my 2 extensions however neither the "Page actions" button nor the bookmark webpage star button were present after the refresh. Solution: Refresh the browser. Right-click on an empty area of whatever webpage. A context menu will popup with a star that appears in the upper right side of that popup window. Make your new bookmark and click "Done". When I did this both my "Page actions" and "Bookmark Star" were back in my address bar. I hope this helps people like me who find either or both of those missing.
