I am logged on to my Chromebook as me. Mrs opens Chrome and is looking for gas hobs. we browse various sites (some direct, some via google - where the images pop up underneath the search bar) including ao.com, appliances direct and currys. Whilst we are procrastinating which hob to get she picks up her mobile and the ads on her facebook (i don't use it so not sure what happened) the hobs we are looking at are in between all the comments. Any idea how that happened?!
