Searching empty string with shortcut "keyword" on address bar no longer navigates to the main site
I don't know which version had this change but not long before, I could type "y " (note the extra space character) and press enter to go to Youtube home page via address bar because "y" is my Youtube search engine shortcut word.
Now, when I try to do that with the latest Firefox, the search bar stylistically changes to indicate I'm searching in Youtube but pressing enter without typing any search term no longer launches the Youtube home page. I don't see the reasoning behind removing this feature, so I'm posting it here to let it be known. I hope the change is a bug and not intended.
