Use Silverlight in Firefox, Chrome in Ubuntu via Pipelight plugin

Last updated: March 21, 2019

Microsoft Silverlight in UbuntuPipelight is a special browser plugin allows to run your favorite Silverlight application directly inside your Linux browser. The project combines the effort by Erich E. Hoover with a new browser plugin that embeds Silverlight directly in any Linux browser supporting the Netscape Plugin API.

Pipelight consists out of two parts: A Linux library which is loaded into the browser and a Windows program started in Wine. The Windows program, called pluginloader.exe, simply simulates a browser and loads the Silverlight DLLs. When you open a page with a Silverlight application the library will send all commands from the browser through a pipe to the Windows process and act like a bridge between your browser and Silverlight. The used pipes do not have any big impact on the speed of the rendered video since all the video and audio data is not send through the pipe. Only the initialization parameters and (sometimes) the network traffic is send through them. As a user you will not notice anything from that “magic” and you can simply use Silverlight the same way as on Windows, like you can see on the following screenshot:

Install Pipelight on Ubuntu

Warning: Before you continue the installation you should note that:

  • It is strongly recommended to close your browser before installing! Some browsers try immediately to load the plugin which might fail or crash the browser when the installation is not complete!
  • Silverlight might contain (like all other browser plugins) security issues – You may want to enable click-to-play for this plugin to prevent an undesired start of Silverlight.
  • Pipelight needs to start Wine to execute the pluginloader. This may slow down the start of your browser.
  • The Pipelight PPA is available for Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 and their derivatives. You can easily install it by running below commands in terminal (Ctrl+Alt+T) one by one:

    sudo add-apt-repository ppa:pipelight/stable
    sudo apt-get update
    sudo apt-get install pipelight

    You may need to accept a license agreement for a set of fonts during the installation. After it’s done just start your browser, type about:plugins in the addressbar and hit enter – if the installation went well you should now see Silverlight in your plugin list and everything is ready to run! Pipelight will install Silverlight on the first start of your browser, this may freeze the interface for several minutes (and you may just see a blank page without any progress). There might appear some dialog asking if Mono or Gecko should be installed during the Silverlight installation – you can safely choose no, as this is not necessary to get Pipelight running. After this step, the overall performance of your browser shouldn’t be affected any more.

    10. hi frustrated
      new to linux mint.

      how do you accept the liciense agreement when installing pipelight in a terminal.
      I followed your instructions and when license agreement appears at the top in ` red ` it says

      Configuring ttf-mscorefonts-installer.

      I left this a couple of times. Each time for 1hr and 10 mins. didn’t work. Tried more times but pressing return to try and accept and doing the recovery sudo. can someone help me?

      • Hi An,
        i had the same issue. Make sure that you closed your Browser. Then open the Software manager and type in the search-box ‘pipelight’. Then klick on result of the search: ‘pipelight’. And then klick install. There will be an window (title:’ttf-mscorefonts-installer.’) now you have to check the check-box and klick confirm.

        i hope it will help you

    11. Can someone please help me out?

      To agree to this license run (for each user who wants to use this module):
      touch $HOME/.config/wine-wininet-installer.accept-license

      Plugin silverlight5.1 is now enabled
      Processing triggers for libc-bin (2.19-0ubuntu6.3) …
