Firefox Sync - about:config settings not applied on other devices

more options

I've just created a Mozilla account so that I can sync my customised about:config settings between devices but I'm struggling to get it working. For each setting I have customised that isn't on the default whitelist, I have created a new boolean setting as follows:

'services.sync.prefs.sync.xyz' where xyz is the setting I have customised.

Each of these newly created boolean settings is set to 'true'.

When I 'sign in and sync' on a new device and check about:config, the values of these custom settings is not changed from the default.

Have I missed something in my understanding of the process?

Any advice will be appreciated.

Hi

As far as I am aware, the preferences in about:config are not synced between devices using Firefox Sync.

Hi Paul,

According to this article they can be synced.

I should have linked it in my initial post to show where I was getting my information from. Do you know of any way to engage with Mozilla directly for support on this?
