Dear developers,
I am writing to suggest removing notification in the address bar, when the new tab is controlled by third-party add-on. This notification is annoying and does not add aesthetic value to the new page. Alternatively (if this suggestion is against some intrinsic Firefox philosophy) it would be good to have an opportunity to use custom wallpapers in both desktop and mobile versions. If implemented, it would be nice if tabs were semi-transparent and changed their color hue based on current wallpaper (similar to Yandex Browser).
