Sync more advanced settings in Firefox (connection settings, Proxy and so on)
does anyone know a possibility to sync deeper, more advanced settings via the Firefox account? For example I'm using network.proxy.autoconfig_url, which is not synced to other machines. I already tried the services.sync.prefs.dangerously_allow_arbitrary setting, but it still won't sync.
Thanks in advance! Juergen

You can sync virtually any setting using the Configuration Editor for Firefox (
about:config page). You simply need to create a preference called
services.sync.prefs.sync.YOUR_PREFERENCE_NAME and set it to
To use your example of syncing the
network.proxy.autoconfig_url preference, you would need to add
services.sync.prefs.sync.network.proxy.autoconfig_url and set that to
What some people forget is that this needs to be done on every device that you want to sync the preference to. Firefox doesn't know that you want to sync that preference, so by default it doesn't include any custom preferences that you have added to Firefox Sync. You'll also have to do this to any new devices that you add in the future.
NOTE: I've found that if you configure your setting first and then add it to Firefox Sync, the value of the setting often gets reset. So, I think it's best to add the preference to sync by creating the preference above first and then change the setting to what you want.
Hope this helps.
