How can I stop pdf files associations continually changing to Firefox?

Since the latest versions of Firefox--say, the last month or so--Firefox continues to override and change my preferred file association for pdf files. I have gone in through the Windows 10 Start/Settings/Apps to change the file association for pdf files to my Adobe Acrobat Pro, but within a few hours Firefox automatically changes it back, system-wide, to Firefox. This is quite frustrating, to say the least. I have tried the Options within Firefox, and choose (as I do for most files) to "Ask Me First" upon opening, but don't find any further file association info there. Nevertheless, even when viewing my files within Windows Explorer (File Explorer), I cannot keep my chosen files association of Adobe Acrobat Pro, as it continually reverts to Firefox.

How can I disable this behavior of Firefox 80.0.1 that is overriding my preference? Or is it a bug that can be fixed?

Thank you for your assistance.... Enten

I am now trying to disable this new feature by setting this pref to false on the about:config page.

   browser.helperApps.showOpenOptionForPdfJS = false 

I'll report back....

Curious... this seemed to slow things down... but did not take care of the problem. I'm still fighting to control which app opens my pdf files, and Firefox continues to override my choice... because this About:Config setting itself was changed from how I set it! (Could that be a Sync issue?)

Can anyone assist, please?

Try to rename/remove handlers.json in the Firefox profile folder with Firefox closed to reset all file actions.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
