How to permanently disable notifications from sites on Android-smartphones Xiaomi

Intrusive website notifications are one of the most annoying features of the modern Internet. Even after accidentally clicking on the “Allow” button, browsers on Xiaomi, Redmi and POCO begin to flood you with ads, news and reminders that interfere with work and distract from important things. Unlike iOS, where notification management is centralized, MIUI-based Android offers several ways to block, from standard browser settings to system restrictions.

To make matters worse, many users don’t know where these settings are hiding, with sites sending push notifications via browsers (Chrome, Mi Browser, Firefox), others via web applications, and some even managing to bypass locks through Firebase Cloud Messaging (FCM) services. In this article, we’ll look at all the current disabling techniques, including hidden MIUI 14/13 features and workarounds for persistent cases.

Why websites can send notifications to Xiaomi

The push notification mechanism from sites works through the Web Push API technology that all modern browsers support. When you go to a site, it can request permission to send notifications — usually a pop-up asking, "Let notifications?" Many users click "Yes" by accident or without realizing the consequences.

The MIUI system can duplicate these notifications through:

• 📱 System Notification Center – Even if you block them in your browser, they can come as “service” messages.
• 🌐 Browsers – Chrome, Mi Browser, Edge have their own lists of allowed sites.
• 🔄 Background Processes – Some sites use Service Workers to send notifications even when the browser is closed.

In MIUI 14 and later, notifications from sites can be disguised as system alerts (such as MIUI News or Recommendations), making it difficult to identify them, making it less likely for users to block ads, but leading to chaos in the notification center.

⚠️ Note: Some fraudulent sites use notifications to spread phishing links. If you see messages like “Your account is blocked!”, “You won a prize!” or “Update card details”, in no case click on links – this can lead to identity theft.

Method 1: Disabling notifications in the browser

The most obvious method is to block notifications in the browser settings you access from, and consider the instructions for the most popular browsers on Xiaomi.

🌐 Google Chrome

If you use Chrome, follow the following steps:

1. Open the browser and go to the site from which you want to disable notifications.
2. Click on the icon. 🔒 (lock) in the address bar on the right.
3. In the “Permissions” section, look for “Notifications” and select “Block”.
4. If the site is not listed, go to Chrome Settings → Site Settings → Notifications and manually add it to the lock.

📱 Mi Browser (standard Xiaomi browser)

Mi Browser is often pre-installed on Xiaomi/Redmi smartphones and has its own notification management mechanism:

1. Open the Mi Browser and go to the ☰ (Menus) → Settings → Confidentiality and security.
2. Select “Site Settings” → “Notifications”.
3. In the list, find the problem site and switch the slider to the “Blocked” position.
4. To completely disable notifications from all sites, move the top slider of “Site Notifications” to the “Off” position.

🦊 Mozilla Firefox

In Firefox, the process is slightly different:

1. Open Firefox and go to the right site.
2. Click on the icon. 🛡️ (shield) to the left of the address bar.
3. Select “Block Notifications” or go to ☰ → Settings → Permits → Notifications for global settings.

Important: If you use Firefox Focus or other lightweight browsers, they may not support push notifications at all – this is a plus for privacy, but a minus for the functionality of some services (for example, the web version of instant messengers).

Method 2: Lock through MIUI settings (system layer)

If notifications continue to arrive even after blocking in the browser, then they pass through the system channels of MIUI. In this case, you need to disable them at the OS level.

Instructions for MIUI 12/13/14:

1. Go to Settings → Applications → Application Management.
2. In the upper right corner, click on ☰ (three dots) and select "System applications».
3. Find the browser (or Chrome/Mi Browser if installed as system).
4. Select Notifications and disable all categories related to web notifications (e.g., Site Push Notifications).

For deeper cleaning:

• 🔍 Go to Settings. → Memory. → Clean up and select Deep Clean. This will remove the browser cache that may contain permission data.
• 🔄 Restart the device – sometimes changes only take effect after a reboot.

⚠️ Note: Some Xiaomi firmware (especially on the POCO With custom shells, the path to settings may be different. If you don't find System Apps, try searching in the settings for browser notifications».

Method 3: Use Do Not Disturb Mode for Filtering

If you don't want to turn off notifications completely, but want to limit them to a certain time, use the Do Not Disturb (DND) feature, which doesn't block notifications forever, but allows you to control their flow.

How to set up:

1. Go to Settings → Sound and vibration → Do not disturb.
2. Activate the mode and select Schedule (for example, from 22:00 to 8:00).
3. In the “Exceptions” section, uncheck “Notifications from Applications” and “Other Notifications”.
4. To lock completely, select "No sound and no vibration".

The advantage of this method is that you can create a whitelist of important applications (such as messengers or alarms) that will work even in DND mode.

• In the same "Do Not Disturb" menu, select "Allow exceptions."
• Add to the list only those applications that are critically important notifications.

Disadvantage: This doesn't block notifications forever, it only limits them in time, but it's useful if you need notifications during the day, but not at night.

Method 4: Blocking through ADB (for power users)

If standard methods do not help, you can use them. ADB-This is a way of forcing notifications to be disabled from browsers, and it requires you to connect your smartphone to your computer and enable debugging. USB, It's 100% effective.

Step-by-step:

1. Turn on Developer Mode on Xiaomi: Go to Settings → About Phone. Click 7 times on MIUI Version until the message “You’re a Developer” appears. Go back to Settings → Additional → For Developers and activate “Debugging on USB”.

Chrome

adb shell pm revoke com.android.chrome android.permission.POST_NOTIFICATIONS

For Mi Browser, use:

adb shell pm revoke com.android.browser android.permission.POST_NOTIFICATIONS

Important: Once these commands are executed, browsers will not be able to send notifications even if you give them permission in the settings. To return functionality, use the same command, replacing revoke with grant.

⚠️ Attention: Misuse of the right ADB Do not follow commands unless you are sure of their purpose, for example, blocking notifications for system applications like com.miui.securitycenter can disrupt the security center.

Method 5: Using third-party applications to block

If you don't want to dig into the settings, you can use specialised notification blocking apps that act as filters to intercept and hide unnecessary alerts.

Top.-3 apps:

How to set up Notification Blocker:

1. Install the app from Google Play.
2. Open it and give permission to access notifications (go to the MIUI settings, where you need to turn on the slider).
3. In the main menu, select “Application Block” and add browsers (Chrome, Mi Browser).
4. For fine-tuning, go to Filters and add keywords (e.g., “subscription”, “promotion”, “notice”).
5. After reset, block notifications immediately: Do not open browsers until you turn off permissions in the settings (see Method 1 and Method 2).

💡

If you reset your settings frequently (for example, when selling your phone), back up only your contacts and media files, eliminating system data, and preventing unnecessary permissions from being restored.
