I think Ubuntu’s web app integration has changed in 14.04. When you create a web app for a service like Gmail, Facebook, Ubuntu will now use the same browser used on Ubuntu Mobile. This theoretically makes web apps more consistent between the desktop and mobile versions of Ubuntu, but it’s a problem if you actually want to use these apps. This browser doesn’t work anywhere near as well and doesn’t even have access to the Flash plug-in.
If you want launcher icons for your favorite web apps, you should probably skip Ubuntu’s native integration features. Instead, install the Chromium or Chrome web browsers and use the Tools > Create application shortcuts menu option to create launcher icons and separate windows for your preferred web apps.
- If you want to uninstall it--
Go to the Software Center and search for the specific web app and uninstall it. E.g.
unity-webapps-gmail or unity-webapps-googledocs
sudo add-apt-repository ppa:noobslab/apps-dependencies
sudo add-apt-repository ppa:folke-schwinning/personal
sudo apt-get update
sudo apt-get install desktop-facebook
sudo add-apt-repository -r ppa:noobslab/apps-dependencies
I think this will work better...
