Dropdown Menus in Firefox Wont Stay Open
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.
