@sgunhouse You say automatically. Does that mean I can turn it on manually? I actually really want Google to know more about me, it make the experience better.

I would really like to make a switch from opera Chrome to opera GX, but before I do that, I would like to know what I miss out on. For example, chrome is always synced with my phone: I can see the tabs which I opened there, when I log into anything googe I get a notification directly on the device and so on. It saves all my passwords and always associates me with my google account. Could anybody tell me what other features I will potentially miss out on?
