Vaadin 6 / 7 / 8
1
  1. Open Firefox 22 (I’m using Windows 7)
  2. go to the “http://demo.vaadin.com/sampler/#ui/interaction/button” site
  3. Press the button
  4. You will see that background does not change (only ‘focus’ is activeted, but ‘active’ css rule is not applied)
  5. Everything works fine if you test the button in vaadin 6 or in different browser (chrome or ie)

Confirmed. Please create a ticket about this in
