Is it possible to move a plugin/extension button/icon outside of the Extension menu?

We used to be able to organize our extension buttons and icons in the toolbar, beside the address bar. However, I just updated Firefox and can no longer show these icons on the toolbar. Instead, they're hidden in the Extensions menu (with the puzzle-piece icon) This is annoying. There are some extensions I use many times a day, like my password manager. Is there a way to move my extension/plugin buttons back to the toolbar?
