I knew there was a "sync open tabs" for chrome so I figured maybe it had that capability (just brainstorming). But looking closer, it just shows your other device open tabs in settings / "recent tabs"If that's not my laptop, how would someone be able to close tabs on my Note 4 from a Windows machine?
One clue is the timing. If you used your laptop last night then that's probably it.There were two Windows machines (the one I'm on and another from last night - was that my laptop, I am unable to tell).
I can't recreate that. Two things come to mind:Just now I was looking at Chrome and saw I had 4 tabs open. When I click on 4 to see the tabs, 3 tabs looked normal. The 4th tab had a title of "New tab", but I could see the top portion of the original page on that tab (it was the tab in the back, so it was mostly covered by the floating 3 tabs in front of it). When I clicked on it, the content disappeared and it was in fact a new tab with google search.
A better example is I've had a few tabs open (relevant articles, pics, etc) to show at the gym. When I arrive, I open Chrome and all tabs are gone. There is only one tab and it's the New Tab google search. All just disappeared.
