Remove suggestion from Firefox autocomplete in url input field

I’m absolutely staggered to have such a hard time finding an answer to this. Now, to make this clear, I am not talking about any of the entries in the dropdown that pops up once you type something into the url bar, so please do not suggest using the arrow keys and pressing shift + delete, that’s not what I’m looking for but seems to be the common answer everywhere. I am talking about the blue backgrounded text that automatically fills inside of the url input field itself.

So, when I type di the input field automatically completes my input with ct.leo.org with a blue background. If I press enter then, I get sent to dict.leo.org, logically. This is not where I want to go though, but instead I would like Firefox to automatically fill in ct.cc, so I want to keep being able to just type in di + enter to get sent to the correct page. I merely want that page to be a different one than Firefox suggests.

Now, wondering as to why Firefox is so reluctantly suggesting this specific site, I assume it’s because in the past I’ve used it extensively until they’ve recently changed their cookies policy, so I decided to switch. Is it possible I have to delete all entries of that page in my history? I would assume there should be a simple to find setting where you could black-/whitelist pages for suggestion or ideally prioritize but I can’t find any; only for the dropdown-list I’ve never cared about.
