So basically I use my side mouse buttons to go back and forth on google pages. A bit earlier this somehow changed. Now when i press the back mouse button it start playing music via Deezer, when i press the front side button it goes to the next song and when i press the middle button it mutes all sound. How can i reset it to the previous settings????
