When you create a custom themes and all your javascript not work on front page, even toolbar module not working, but the toolbar run normally on admin page, you have same problem with me. Follow this instructuon :

Check your libraries file (yourtheme.libraries.yml) make sure you have only one jquery refference. Example :

global-styles:
  version: 1.x
  css:
    theme:
      css/styles.css: {}

global-scripts:
  version: 1.x
  js:
    js/scripts.js: {}
    js/responsiveTabs.js: {}
    js/ jquery   <- comment or delete this
  dependencies:
    – core/jquery
