Disable Viber Notifications (Ubuntu Flatpak Version)

Follow these steps to stop Viber from interrupting your typing or switching your active window.

1. Open Viber

Launch the Viber application from your applications menu.

2. Go to Settings

Click the gear icon in the upper-right corner of the Viber window.

3. Select Notifications

In the sidebar menu, click Notifications.

4. Turn Off All Notification Types

Inside the Notifications section, switch off the following items:

1-on-1 messages

This prevents Viber from triggering pop-ups or requesting attention.

What is "Focus Stealing"?

"Focus stealing" happens when an application forces itself to the front or grabs the keyboard focus while you're actively using another window. On Ubuntu, this can cause:

Keystrokes going into the wrong app
The active window losing control
Your typing suddenly doing nothing

Some apps do this when displaying notifications. Disabling notifications prevents Viber from grabbing the focus and interrupting your work.
