There are some web apps that I decided not to install initially; I selected "Do not ask again" for the prompt. Now that I have changed my mind, how do I go about installing that web app for a particular browser?

Open the software center and search for unity-webapps. There you can install the ones you want.

enter image description here

You can also use the command: sudo apt-get install unity-webapps-<webapp-name>

Make sure you have the following packages installed:

unity-webapps-service libunity-webapps0 xul-ext-unity libufe-xidgetter0  

You can install them with:

sudo apt-get install unity-webapps-service libunity-webapps0 xul-ext-unity libufe-xidgetter0
  • Thanks, I did that and when I re-open the software center it shows that it is installed. However, when I visit the website (Google+ in this case) nothing happens.

  • That still didn't do the trick; I've been using Firefox for a couple of days now and the option to add webapps for neither Google+ nor Facebook popped up.
