I have Firefox and Google Chrome installed in the same machine (Linux). It happens when I type something in Chrome Omnibox it suggests pages I have already visited in Firefox.

  • I have never connected the accounts of both browsers
  • I have never imported information from one browser to other
  • I have never visited the suggested pages in Chrome
  • The keyword I type in the omnibox is vague and there is no way it could guess the suggestion without having access to the Firefox history. i.e.: i type "ir" in Chrome and it suggests me the same Iron Maiden lyrics page I have browse before in Firefox.

    Do you have any synchronization extensions like Xmarks installed? Jan 19, 2013 at 20:00
  • No, I dont. It is a clean installation.

    Could it be that you're logged into Google, which remembers your previous searches an auto-suggests them?

    @fdisk Is the history actually showing up in your chrome://history/? Or is the omnibox simply just guessing your searches pretty accurately?

I don't remember the Chrome installer ever asking for permission to pull your history.

Since the firefox history is in a set location, it is not hard for Chrome to pull it without your express permission.
