How to delete address bar suggestions [duplicate]

Highlight the entry and:

• Shift+Delete on a PC
• Shift+FN+Delete a Mac

To disable autocomplete in general

• open the Chrome Settings
• Show advanced settings (at the bottom)
• Under Privacy, uncheck
  • "Use a prediction service to help complete searches and URLs typed in the address bar."
  • use a prediction service to load pages more quickly

The completions will still appear as dropdown items and you can arrow down to select them - if you want to, but they won't be automatically applied.

Chances are you have the site bookmarked

Enter the site so as it does show up in your browser history. Then go into your history, you'll probably see a star at the end of the url in the history page. Click on that and it'll remove it from bookmarks, then you can delete the site normally.

On linux (ubuntu) with chrome: while starting typing and then having specific item highlighted as suggestion: Crtl + Shift + Delete
