Apparently, this behavior is caused by Chrome sending the special GET parameter &espv=101 in the URL.
You should be able to fix it by simply removing the parameter (along with all the other junk that Chrome sends by default):
- Right-click the Omnibar
- Select Edit search engines…
- Select Google (Default) and click
[Edit] (or just double-click it)
- Replace the
URL field with https://www.google.com/search?q=%s
- Click
[OK] and [Close]
Now, when you type something in the Omnibar, it will go to a nice, simple, encrypted Google search without sending all kinds of extra information to them, and without removing the search box.
