Are you setting up the new user, or do they do it themselves?

One way would be to set up your default profile, then link it to the sync servers. When a new user creates a new profile, sync that profile before doing anything else. Once the data is loaded on the new profile, remove the sync link.

If you want to change the data, just change it. It will replace the data on the sync server. But any already created 'copies' would have to be done as well.

Note: With sync, there is no master. The data goes both ways. That is why I said above: sync that profile before doing anything else.

As to the data choices (bookmarks, settings . . . . ) it's an all or nothing choice.

Thanks for the reply.

What if I don’t want to use sync? I have many users which don’t currently have accounts so there will be an issue getting those all created.

Also when users leave the company I don’t necessarily want them to be able to retain all the info that is stored.

You posted under regular Firefox instead of Enterprise, so I flagged this thread to be moved. Hopefully those folks will have a solution for you.

By the way, when you mention a previous version, was it in the Firefox 60 ESR series, or do you mean Firefox 52 ESR?

Ok thanks for flagging to move.

Previous version was 52 ESR

Support for the defaults/profile directly was removed a while ago.

What specifically do you want to preconfigure?
