Dropdowns will not stay open
When I click to open a dropdown, it opens and then immediately shuts back up again. I have to maintain pressure on the left click to keep the box open. Any ideas?

I would try a new profile. You can create one with Firefox open or closed.

Terry, thanks for your response which I tried but unfortunately it didn’t solve the issue.
I can't see which OS you use. Windows and Mac have particular issues with which I am not familiar. Providing more information may improve your chances of finding a solution.
Otherwise, if a new profile doesn't solve the problem, you could try reinstalling.
The OP is on Mac OS 12.6.
If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version
Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.
- click the shield icon for more detail and possibly disable the protection
You can check the Web Console for relevant-looking messages about blocked content.
You can try these steps in case of issues with webpages:
You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.
- hold down the Shift key and left-click the Reload button
- press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
- press "Command + Shift + R" (Mac)
Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings).
"Remove the Cookies" for websites that cause problems:
- Settings -> Privacy & Security
Cookies and Site Data: "Manage Data"
"Clear the Cache":
- Settings -> Privacy & Security
Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
cor-el Thanks for that very comprehensive list of things to try. Unfortunately none of them has worked. properly. However, I did notice that after doing a couple of your suggestions the behaviour was slightly different. When I am logging into my bank website there are 3 drop-down boxes in view asking for random characters from a password. When I click the first of those boxes it behaves normally, ie I can click and then scroll down the alphabetic list of characters to get to the appropriate letter. But when I then click the second or third box, the list of characters still flashes down and then vanishes.
I have spent many hours trying many possible "cures" for this disappearing dropdown list problem but to no avail. One thing I did pick up somewhere was that it might have something to do with the size of the window in use. Sure enough, when I reinstalled Firefox for the Nth time the dropdowns all worked in the very first window that opens. However if I resize it, all goes to rats again and resizing back to the original size doesn't change that. So, I either have to live with it, or it's back to Safari, where I detest its slowness and it's variable size tabs. Chrome is fine except that it and all the Google stuff in adds, slowed my Mac to a crawl. Over and out.
