Hello everyone, I am experiencing this issue since - I suppose - Firefox Sync existed. My main machine has - like any other machine I own - Firefox always up to date and a set of plugins like No-Script, an ad-blocker, a theme, GUI icon disposition and whatnot. When I install Firefox on a new device or machine and then proceed to sync them, I lost the theme across all my synced devices, ALL of the registered sites I have trained No-Script and the adblocker not to block and my GUI settings. In short every new machine with a fresh install and sync of Firefox will wipe and overwrite to its defaults any synced custom configuration I have. Is there a solution for this?

Thank you.
