No, there is no possible way to do that remotely. But there is one not official way and For that you have to follow the following:

1. Sign in for Firefox Sync
2. In your Sync option Choose "preferences" leaving others, this will only sync your preferences not your passwords or Bookmarks. Goto Menu>Options>Sync
3. Now from all your Firefox sign in to that same sync account, now you can control your employees remotely.

i mean is there a way to enable check for update without having to go on each pc to enable the feature ?

Thanks

You can use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values for prefs.

Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg.

pref("general.config.filename", "mozilla.cfg");

These functions can be used in the mozilla.cfg file:

defaultPref();	// set new default value
pref();		// set pref, but allow changes in current session
lockPref();	// lock pref, disallow changes

Thanks

but not sure what to put there to enable the check for update and the silent install with the background service.

You don't need to go to every computer and check for updates manually. Firefox automatically checks for updates regularly.

Please be aware that within the first couple of days, not all users will be updated automatically at once, that should be happening later this week.

well yes cause before we disable it when we install firefox but now we want to reenable it but i don't want to go to all pc one by one Thanks
