Thanks for the debug output.  Chrome seems to think you've visited that page at least three times, most recently ~11 days ago.  Handing this off the navigation folks, who may know how to investigate.

CCing some folks you might be able to guess how that got into your history (as a typed navigation no less)

Sorry, no good ideas.

The only theory I can come up with: If you travel to a place with a different Google TLD, then that URL would not be considered the "NTP URL" anymore, so it might end up in your history. But presumably, that wouldn't count as "typed".

lgarron@, are you still seeing this?

If so, can you please provide me (mpearson@) directly with your History file so I can see if there is a referrer listed for the visit to that new tab page?

Also, does trieb@'s idea in comment #3 sound like something that might've happened to you (switching Google TLDs)?

Yes.

Shared via Google Drive!

Possibly. I regularly test with other locales and travel to other countries. I don't recall for sure if either was the case when I filed this bug, though.

This history file shows 29 visits, all typed, and all with transition type 805306369.  If I'm doing my math right, this corresponds to
PAGE_TRANSITION_CHAIN_START | PAGE_TRANSITION_CHAIN_END | PAGE_TRANSITION_TYPED.
https://cs.chromium.org/chromium/src/ui/base/page_transition_types.h

Most importantly, and most troublingly, all these entries have no |from_visit| listed, i.e., no referrer.

The omnibox really thinks this an ordinary typed navigation.

lgarron@, I assume you're not actively selecting this URL, right?

(I'm curious about the increase in typed visits from 3 when you originally reported this bug to 29 now.  Was this caused by you using the suggestion?)

> lgarron@, I assume you're not actively selecting this URL, right?

I don't think so.

Interestingly, I visited France 2 weeks ago, and I now see the google.fr new tab URL in autocompletions. I'm *pretty* sure I didn't explicitly visit that URL or select it for autocompletion.

Any other debugging I can do?

Or is there an easy way for me to clear all related data and observe if it happens again?

That screenshot is from my Chromium profile, but it's *also* happening in my work profile.

Even better, this is happening in my work and Chromium profiles on my workstation, which has never left the country. But they sync with a laptop that has.

I'm going to assign this to treib@, as he best might know how to investigate or re-assign this further.  It's fundamentally a history/navigation issue caused by something on the NTP.  The omnibox is just a symptom.  I've done the best I could, now for someone else with more relevant expertise.

By the way, thanks lgarron@ for all your detailed answers!

It does seem to be related to changing TLDs somehow: If I manually visit "https://www.google.com/_/chrome/newtab" (while my Google domain is .de), then that does show up as an Omnibox suggestion. This seems somewhat reasonable.

Curiously, visiting "https://www.google.fr/_/chrome/newtab" doesn't seem to make that show up as a suggestion for me.

Anyway, the biggest mystery is where those TYPED navigations are coming from. I have no idea about that...

It seems that "google.com" (as well as many of its prefixes) now autocomplete to "google.com/_/chrome/newtab?espv=2&ie=UTF-8" for me. :-/
