Or surf normally and it should eventually balance itself out. My suggestion is if you are going to be away for a long period of time, either close the browsers before stepping away or shut down the laptop. It might be inconvenient for some of your pages, but a two year old laptop is quite quick.

I am so used to Google. It will take me a bit to get used to Edge.
