Selecting item from select menu erratic

When I click on a select menu to choose an option it either flashes up and then closes before I can select or I select an option and it closes without changing to my selection. If I hold down the left click it keeps the menu open and I can then choose my option, the dropdown closes but hasn't selected my choice of option. Attached is an animated gif demonstrating the problem

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86)

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove the profiles folder.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

Before I try this, I should say that I also have the Firefox Developer Edition installed and it has the same erratic behaviour when selecting from a select menu.

It might be best to remove every program and start over. You can reinstall Developer Edition later.

I've removed all Firefox from the applications folder, rebooted and then installed Firefox again. Same problem with select boxes.
