I'm seeing a strange issue on Google Chrome across two computers (one Windows, one Mac).
Whenever a Google site includes a search box, such as on the search results page or even Google Calendar, Chrome is autofilling a previous search term. This triggers Google instant search and displays the results from that search.
It's not happening in Incognito mode, which makes sense. I've tried clearing my cache and form fill entries.
I do use LastPass, but I can't recall ever seeing it cause anything like this.
