My wife currently accesses her Facebook account from two computers, her PC and my laptop. During the course of her Facebook activities she has gradually accumulated a number of 'link-ins' from various sites so that when either PC visits these sites, a corresponding note appears on my wife's Facebook timeline. This tracking is undesirable - she doesn't want to know every time I visit for example
www.guardian.co.uk from my laptop. Note that I have nothing to hide, you understand, but there is a principal thing going on here.
So... How can I remove all traces of my wife's Facebook account from my laptop (but not the actual account itself, of course), so that I can visit these pages without her Facebook account being updated with details of what I visited?
