Thunderbird - disable new message popup notification for specific account, sender or folder

Problem:

You have 2 or more accounts in Thunderbird. You want to receive notification only for one of them.

Thunderbird just allow you to enable or disable notification (for all accounts). If you need this, just go to Edit-> Preferences and disable Show an alert. Disable Play a sound too. This will disable notifications for all accounts.

Instead if you need disable notifications only for ONE account, read the Solution section.

Solution:

Install a Thunderbird extension.

Step by step:

Install Mailbox Alert extension. In Thunderbird choose Tools -> Add ons. Search Mailbox Alert in the textbox (located up-right).
