I'm using Firebase for push notification. Problem is i want to send push notification for some mobile phones but when i'm sending push notification it will send notification to all installed mobile app
You would need to get the mobile token and then store it somewhere on your server.
Then you can send to specific devices using the mobile token.
Just in case, i actually wrote a full guide on how to implement push notifications to your ionic app here

I'm using Firebase to send notifications to my React Native frontend. Notifications come through fine when the app is closed, but user's don't receive the notification while they are inside the app. How can I force the notification through every time?
the notifications are received but not showing when the app is open (foreground) you will have to use this or similar solution to show the notification on the screen in this case.

I have used it on android and iOS with no problems.
You can't "force" them but you can handle them
I have completed an e-commerce app in ionic3. The problem is I want user to be notified when new offers or deals are added in our inventory. This should be a backend process, whether or not the app is open or close.
Note: There is no firebase involved.
If you want to use to get notification in same device then you can try Local notification native plugin for notification and if you want to send notification to other device then you have to use Push or FCM or Onesignal and yes this all required firebase to send push notification to generate device id/key.
I am sending push notifications using Flutter's firebase_messaging package and I send them in the firebase console. When the app is in the background or when it is closed, I am receiving the notifications, however, when the app is in the foreground it is not working. Please tell me if I need to integrate Javascript to make this feature work, and please reference a resource that I can use in order to figure out how I can integrate Javascript with fcm as I haven't found a way to do this with flutter.
I figured out that someone can use the flutter local notifications plugin so that when the push notification is sent and the app is on the foreground, normally no notification would be delivered to the system tray, but using the flutter local notifications plugin, it would be possible to send a local notification when the app is on the foreground.
To Understand better.
Have a look into this table.
https://pub.dev/packages/firebase_messaging#receiving-messages
It states that when your Android or iOS Application is in foreground, OnMessage callback is called if you are sending notification payload or data payload as notification body.
You are receiving notifications when your app is in background because, when an app is in background notification is send to system tray and OS (Android or iOS) handle it for you. And your app is launched when you click on notification from system tray.
When your app is in foreground you have to catch notification payload in onMessage and handle it explicitly, you can create local notification in this case.
I unity developer, I used "onesignal.com" to send push notification to my active users. Now please guide me is there any way to send messages to those who have un-installed my app ?

Push notification not receiving to my IOS device which is working fine for android. I am using Firebase to send notification for android and IOS, I have configured the google-service-info.plist file to my Firebase account and enabled push notification in Xcode before taking the build. But I am not able to receive the notification, is there any additional configuration that I required to change for IOS? Why am not getting push notification which works fine by default for android?
I am able to get device token of IOS that am using this token to trigger notification.
if you are still having this problem with ios push notification. This is how i solved it.
Login into your apple developer account and create an APNs Authentication key (.p8 file).
Then upload it to your firebase console in the cloud messaging tab.
