Just recently switched from Chrome to Firefox, something that annoys me is lack of support for touch screen as I uses surface pro for lighter tasks. Such as swipe right to go back, swipe left to forward. Given the fact that there is a good number of touch screen laptops in the market, this feature should be added. I wish could use Firefox on my surface so all my tabs and history stays synced, but until touch screen support is added, I have to stay with Chrome.
