Ubuntu – How to uninstall apps installed through Firefox Marketplace

14.04firefoxuninstallwebapps

In Firefox 35, there is menu called "Apps" that allows to install "firefox apps" through Firefox Marketplace. I installed an app but now I can't find how to remove it! Is there an obvious way that I cannot see?

I am using Ubuntu 14.04.

To uninstall Firefox marketplace apps from your system, you should go to Home directory and unhide all content by pressing Ctrl+H. Then, navigate to the file/folder and copy the file name, after that open the terminal by pressing Ctrl+Alt+T and run following command (replace the .appname-hash with the original application).

Where appname is a recognizable descriptor for the app, and hash is an arbitrary string of characters. On my Linux machine, this Rechargeall app installs to ~/.rechargeall-2d7d25496791e76f039bfc4bcd24ca7a.

~/.appname-hash/webapprt-stub -remove

For example:

~/.rechargeall-2d7d25496791e76f039bfc4bcd24ca7a/webapprt-stub -remove

Ubuntu – How to uninstall a firefox plugin

As per my comment on the question, mozilla provide some instructions for manually uninstalling.

Manually uninstalling a plugin

If you can't use an uninstaller program to remove a plugin, you can remove it manually:

In the Location bar, type about:config and press Enter.

The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.

Search for the preference: plugin.expose_full_path.

Double-click on the plugin.expose_full_path preference in the list to change the value to true.

Enter about:plugins into the Location bar to display the About Plugins page.

Each entry in the About Plugins page will have "File name:" followed by a path. Use Windows Explorer to navigateNavigate to the folder shown for the plugin you want to remove.

Rename the file to something other than its normal name - e.g. npswf32 becomes Xnpswf32

Double-click on the plugin.expose_full_path preference in the list on the about:config page to change the value back to false to avoid exposing the plugin path to websites.

The plugin will be removed.

Ubuntu – How to remove Unity web apps

Ubuntu 13.10 and 14.04

To avoid being asked for webapp integration you can use the following command, open a Terminal (Ctrl+Alt+t) and type:

gsettings set com.canonical.unity.webapps integration-allowed false

Tested on both releases with Firefox/Chromium + Launchpad, Facebook and Youtube. No popup asking for a webapp integration.

Removing existing webapps

We can't just remove all packages beginning with unity-webapps- as some of them are runtime dependencies of Unity or other packages (like the Ubuntu SDK which requires unity-webapps-qml)

A safe way is to remove such installed packages not belonging to the gnome section:

sudo apt-get remove $(dpkg-query -W -f='${db:Status-Abbrev} ${binary:Package} ${Section}\n' unity-webapps-* | awk '{if ($1 == "ii" && $3 != "gnome") {print $2}}')
