There are <b>services.sync.prefs.sync<pref-name></b> prefs with a value true for each pref that is by default included in syncing preferences. You can set the corresponding <b>services.sync.prefs.sync.<pref-name></b> pref to false to prevent syncing this pref. * you can set the <b>services.sync.prefs.sync.browser.startup.homepage</b> pref to false on the about:config page to prevent syncing the home page setting * prefs that have a corresponding <b>services.sync.prefs.sync.<pref-name></b> pref that is set to true will be synced to other devices * prefs that have a corresponding <b>services.sync.prefs.sync.<pref-name></b> pref that is set to false will be excluded from syncing * if you want to sync prefs that are currently not included then create a corresponding Boolean sync pref and set its value to true ** services.sync.prefs.sync.<pref-name> (omit the <>) You can open the <b>about:config</b> page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue. *http://kb.mozillazine.org/about:config
