Google is now rolling out a system where Chrome directly tracks your activity and shares its summary with advertisers.
Also Firefox is faster as of like two months ago.
It takes five minutes to switch browsers, and the difference is so little that you’ll often forget you did it.
Not sure if this Chrome thing also applies to mobile, but this is as good time as any to remind people that you can now install uBlock Origin (and many other useful extensions) on the android firefox app.
