> somehow my buttons on hover does not have a blue borders

The blue border only appears when the buttons are focused.

To trigger this you can either:
- manually move the focus: click the URL text input next to the buttons and then use shift+TAB to move the focus back to one of the buttons
- use the browser toolbox:
  - press cmd+alt+shift+i 
  - a Multiprocess Browser Toolbox window should open
  - use it to inspect one of the buttons of the about:devtools-toolbox tab
  - force the ":focus" pseudo class
