Since last update of Firefox USR (now in version 68.2.0 , 64-bits), I can no longer change from one window to another by clicking in tab icons within the add-on own pop-up window... Besides this current bug, it works great!
Hi André, could you please try the latest version - it should be working correctly now? We put in a lot of time into debugging this. Kindly let me know if this is fixed for you now
