Recently I've been having trouble with the dropdown menus in Firefox, such as the History and Bookmarks menu in the tool bar and the right-click menu. Intermittently when I open the menus they close within a second or two without me doing anything. This only happens in the Firefox window, all of my other apps and browsers are fine.

I'm running on a Macbook Pro with OSX 10.15.1 and Firefox 70.0.1. I've restarted Firefox and it fixes the problem for a short time then the problem returns. I've cleared my History, including Caches and Cookies, reinstalled Firefox, restarted my computer and tried disabling my add-ons. The issue keeps coming back.

Chosen solution

There is a workaround to make firefox dropdown open forever.

Steps:

1. visit about://debugging 2. click any "Inspect" button in the page 3. top right corner of the opened page, click "..." 4. in the dropdown menu, check "Disable Popup Auto-Hide".

Note that this isn't limited to the about:debugging page, but is merely a setting in the developer tools that allows to inspect content in a drop-down menu.

This controls a pref on the about:config page.
