If you are one of those who do not use web applications in Ubuntu and you hate the notifications that skip every time you visit a page that supports the desktop integration of the Canonical distribution asking if you want to install your web application, then you will probably want to disable these notifications once and for all.
When a warning pops up warning of the possibility of integrating a site into your Ubuntu desktop there is an option to disable notification for that site (Don’t ask again), But if you want to disable notifications for all sites you need to pull then another solution.
One is to go to the preferences of Firefox (Preferences → General → Desktop Integration) And uncheck the option Ask about integration options for any website. Ready, desktop integration notifications have been turned off for all sites; the problem is that this only works if we use the Mozilla browser.
Unity Tweak Tool
The most effective option for disable website integration notifications with the Ubuntu desktop comes from the hand of Unity Tweak Tool, A powerful tool for configuring various aspects of Unity that can be installed with the following command:
sudo add-apt-repository ppa:freyja-dev/unity-tweak-tool-daily && sudo apt-get update && sudo apt-get install unity-tweak-tool
The application has in the latest version a section dedicated to Ubuntu web applications (Web Apps). All we have to do to turn off notifications is go there and turn off the option Prompt integration, As fast and easy as that. From now on, notifications will no longer be displayed, regardless of the program we use to browse the web. And if at some point we changed our mind we just have to return the option to its original state.
