Some users have complained that the drop-down menu in Firefox is not working, such as the History and Bookmarks menu in the toolbar and the right-click menu.

Dropdowns are a widespread interface pattern used for navigation menus, language selectors, and as components in more complicated interface elements.

We know it can be quite infuriating when you try to open the menus, but they close within a second or two without you doing anything. It becomes even worse when you get to know this only happens in the Firefox window, while all other apps and browsers are fine.

What to do when the drop-down menu is not working on firefox? Don’t worry, read below as we’ve provided some fixes in this article.

Why can’t I see the drop-down menu when I click it?

If the menu bar is not visible or accessible, your Firefox installation may be corrupt or even damaged. It is also possible your computer has malware that is preventing the menu bar from being displayed.

Users coming from earlier versions of Firefox may notice that the menu bar, containing the File, Edit, View, History, Bookmarks, Tools, and Help menus, appears to be missing. In the newest versions of Firefox, the menu bar is hidden by default, to give you more screen space for browsing.

Another thing is that the application may have been programmed temporarily. This shows the file menu bar and allows users to use any of its features. The menu bar is located above the address bar, in the upper-left corner of the browser window.

How do I get a menu bar in firefox?

Press the Alt key to temporarily show the Menu bar (if the Alt key doesn’t work, press the AltGr key.) To always show the Menu bar: Right-click the top of the Firefox window and click the Menu bar.

If pressing the Alt key does not make the menu bar visible, try pressing Alt+V. This keyboard shortcut opens the View menu, even if the menu bar is hidden.

Quick Tip:

Another practical and efficient method to bypass this issue on your PC is by switching browsers with Opera One.

This experienced browser delivers plenty customization features like mouse gestures or multiple workspaces. Other built-in features are Ad blocker, VPN and an AI.
