Can I disable or change the sound I hear each time a popup is blocked?

Yes, you can. The "Popup blocked" sound is controlled from Popup Killer tab. To open it:

• Select Popup Killer tab.

To disable the sound click Clear button in Popup Killer tab. To change the default sound to your own sound, click "..." button and select your sound file from disk.

Do not forget to click OK button if you wish to save your changes.
