Can I make it so that the link does not appear in the address bar?

Question

Browsers

I set my own start page (.html with a set of necessary buttons) when opening a new tab, and when it opens, a link to it hangs in the address bar (file:///home/eve/...). Is it possible to make the link not appear because I often use the address bar and it's inconvenient to delete it every time?
