The URL of this page made me realize Firefox is happy to display spaces in URLs where Chrome will not.
Does Firefox not replace spaces with %20? It does for me.
It matters what your security settings for URL display are. There are attacks related to the URL bar (of course), so you can set Firefox to only display the raw urlencoded URL, or display emojis/non-ASCII characters visually. I guess there is theoretically ideograph attack mitigations in the second mode, but I don't trust it enough for the small benefit as an English language user.
