How to deploy handlers.json file to all new profiles?

I edited a handlers.json file for our users that I would like to push out for all new firefox installs. I tried placing this file in the "defaults" folder in my firefox directory, but it doesn't appear to be correctly copying over to any new profile made. If I manually copy the handlers.json file to the new profile folder, I do see the changes reflected.

Where do I need to place this file in order to push it out? I tried <firefox>/defaults, <firefox>/defaults/prefs, <firefox>/browser/defaults and none appeared to work. I did paste my code contents into a linter to verify there were no errors.

Thanks.

Firefox doesn't support the defaults profile folder. There's no really easy way to do what you're asking. I've written some code that does this but it will only work on ESR starting with Firefox 62.

I'm going to investigate adding handlers support to our policy engine.

Did you try this folder in the Firefox installation folder?
