Initially I loved the concept of the tab grouping, but seriously I keep wasting hour of my life because the tabs keep crashing or disappearing or scatter all over the place after iv organized them over and over again. I never know what I am going to find when I open my browser. I just lost everything iv been window shopping for, things like cloths for myself for the summer and wedding anniversary stuff for my wife. Fix this please. I hate this now, would give a 0 if I could.
