Allow addons to clear the URL input

[Kinomori]

When using an addon to change which page is used for new tabs, a new problem arises where the URL input is now filled with the website you changed it to, betraying the old functionality of having an empty URL bar with new tabs. Suggestion is to allow addons to clear the URL input so new tab addons can restore base functionality and increase quality of life.
