In Firefox android the video player had play and pause button and video timeline.. "If you want seek you need to work it out through timeline bar and you also hold phone in one hand and other hand finger swipe the timeline bar to seek.. if you put 10sec forward seek or 10sec backward seek (Like youtube had) it will be easy to use seek between video in single handedly" so as a common user it will frustrate using both hand everytime to seek video i believe in future update it will be fix.
Thank you 🤞
