It deleted all my tabs in groups that I had been saving since four months. I had been regularly checking on the Manage Tab Groups option and one day when I did, all the tabs had just vanished God knows where. Horrible App.

Apart from this deceit, it used to download STG performance files everytime I used Firefox which I did not want on the system.

Horrible User Interface as well. I just put up with it in the hope that atleast it will help me function well.

Save yourself the misery by not using this app and try any other but this.
