policies.json don't work on Windows

I've made "C:\Program Files\Mozilla Firefox\distribution" folder and policies.json with test policy below: {

 "policies": {
   "SearchBar": "unified"
 }

}

But it doesn't work. In registry it does. I even used Enterprise Policy Generator to exclude any typos. What's wrong here?

Ok I know what the problem was. I had an inactive different policy in the registry HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox When I removed it completely, JSON started working again.

Didn't know that even a one (although totally different one) policy in the registry can block JSON. We learn something every day.

Case closed.

Do any policies appear on the about:policies page after starting Firefox? If not, it seems Firefox either isn't reading or isn't understanding the file contents.

Did you use the extension's download button? If you copy/pasted to an editor, please double-check that there's no unusual formatting in the file (it is plain text) and that there's no hidden .txt file extension.

That is interesting. I don't know whether it is supposed to work that way.

It is supposed to work that way for now, but I've got a fix going into Firefox that will make them coexist (although GPO wins when there is a match).

The fix is in, just not sure it will be uplifted.
