Just updated Firefox, where did the button that minimizes the toolbar on the top right go? It makes it so all you see are the tabs.


The url box and everything but the tabs of my websites are gone. I like that button because full screen on some videos doesn't work and I can at least use that button to make videos bigger.

Hi Aleshia,

Go to View - Toolbars and click on "Customize". The button you are looking for is called "Full Screen" , you should be able to select it from the list and add it back by dragging it to your Toolbar.

I think you might be in fullscreen, press F11. How to make Firefox and websites go full screen

Thanks, but that's not the same button that I am now missing after my update. After using this toolbar minimizing type of button I could still see my icons on the bottom of my screen & I still had some of the bar of my browser, it just had the website tabs and the red, yellow, & green buttons on the top left.

The first picture shows how my screen looked before I hit the button you see on the top right, the next shows how it looked after. That is the button I want back. I could still move from tab to tab & I could move the window around.

You may have run a Firefox version in the past that didn't fully support full screen mode on Mac.

There are toolbar buttons available to show/hide specific toolbars.
