Firefox no longer able to open SharePoint documents in app - "one of the following protocols (ms-word) isn’t associated with any program or is not allowed"
I've been using Firefox for many months and rarely had issues with this, but I've been unable to open documents from SharePoint to the MSFT apps on my computer for the last two weeks. When I have a SharePoint link that I need to open, one of two things happens: - if I right-click on the link and select "open in Word" (or whatever MS product I need), I get the following error message: "Firefox doesn’t know how to open this address, because one of the following protocols (ms-word) isn’t associated with any program or is not allowed in this context. You might need to install other software to open this address"
- If I open the document in the browser and then select "Open in app," it indicates that the app has been opened but nothing happens.
Any ideas on how to fix this?

I tried each of your ideas and had no success before the holidays, but came back from vacation and it had mysteriously fixed itself. I wish I could identify which solution made the difference, but regardless thank you all for your help!

Perhaps this is already set up, but just in case:
You could try creating a new preference for ms-word and see whether that helps. Here's how:
(0) Select (triple-click is fastest) and copy this new preference name
network.protocol-handler.external.ms-word
(1) In a new tab, type about:config in the address bar and press Enter/Return. Click the button accepting the risk.
(2) In the search box above the list, paste the new preference name
If this is already set up, Firefox should show a bar for the preference with either true or false. If it is false double-click it to switch it to true. If you don't see that bar:
(3) Firefox should show a bar with the choices Boolean, Number, and String. Click Boolean then click the + button at the right end of that bar.
(4) If Firefox doesn't set the value to true automatically, double-click the new preference to switch the value to true
Does Firefox handle the links any better now?
You might want check that a Windows update hasn't changed your protocols.
