Status bar hide and full screen

I'd like to suggest a few features that would make browsing on Android much better. First, please add an option to hide the system status bar while browsing, so web pages can use the full screen for a cleaner, more immersive experience. Second, it would be great to have a true full-screen mode when watching reels or short vertical videos on any website, without the address bar or other interface elements getting in the way. Third, please let users pin their favorite extensions to the toolbar or main menu, so they can reach them in one tap instead of digging through the extensions menu every time. Finally, I'd love an option to show the open tabs and new tab buttons at the bottom of the screen instead of the top, since that's much easier to reach with one hand on today's large phones. I believe these changes would make Firefox more comfortable and competitive on mobile. Thank you for considering my suggestions, and keep up the great work!
