? Can you attach a screenshot of your menu?

Here's a random screenshot from VLC's website. If I click on the 3 dot menu or hamburger button I have a menu item for extensions. But in Firefox desktop I have a toolbar that shows the symbol for extensions plus a few extensions that I pinned there for easy access, like the Video Downloadhelper extension. I have Firefox on all of my android devices and I can't get the toolbar to display on any of them. To be completely honest, I don't even know if the toolbar can be displayed on Android mobile devices, like tablets or phones. Thanks for responding and for your help.
