Unity3D Web Player and Other Windows Plugins under Linux Browsers – Pipelight Project

Unity3D Web Player and Other Windows Plugins under Linux Browsers – Pipelight Project

Warning: When you see an option with –, please remember that it’s two hyphens (- and -), but WordPress makes them to be one dash! For example, –update.

Remember: When you are installing Pipelight, your browser should be closed. If not, you will have serious troubles with running the plugins. If you have still errors, just close your browser and install Pipelight again.

I could run Unity3D on Linux, but there’s a problem with Unity3D Web Player. Pipelight Project seems the best idea as to porting Windows Plugins to Linux browsers. It was started by FDS-Team from Germany.


Pipeline Project:


I tried with Unity3D Web Player in the past, but achieved nothing; however, there are people who were able to run it on Linux with use of Pipelight Project. FDS Team helped me, and Unity3D Web Player is running on my browser. You will be successful, too. Just follow the instructions:

Unity3D Web player on Linux

zypper ar –refresh http://download.opensuse.org/repositories/home:/rbos:/pipelight/<openSUSE version>/home:rbos:pipelight.repo

zypper ref

zypper install pipelight

<openSUSE version> – your openSUSE version. Packages are currently available for openSUSE_12.2, openSUSE_12.3 and openSUSE_Tumbleweed. Unfortunately, I use openSuse 13.1. So if you have the same problem, go to the website:


But before you install the pieplight package, you should have some dependencies installed on your system:



You can download them from


Just write the package names you search.

Then, install the pipelight package:


from the repo:


The installation of the Windows plugins takes place when you start your browser the next time. However, you probably will need to install a User Agent Switcher (or User Agent Overrider) for some of the plugins so that they can work at all. In other words, sometimes, you should cheat websites that don’t support browsers installed on Linux. User Agent Switcher and User Agent Overrider can help you to do that. Sometimes, it’s troublesome, so seek information in the Internet.

I use User Agent Switcher for using Unity3D Web Player. User Agent Overrider doesn’t work for me. After having installed this extension in your browser, for Firefox, go to:

Tools -> Default User Agent -> Edit User Agent -> New

Description: Safari 534.55.3 (OS X 10_7_3 Intel)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.55.3 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10

All next lines empty


Refresh the WWW page to use the new user agent and the plugin or just restart the browser. Remember, this user agent work well for Unity3D Web Player; for other Windows plugins, you probably have to change to other. To get more details, go to:


A full user agents list:


Ok, so your pipeline is installed and works. You changed user agent to one that is welcome. All should work. Some of the Windows plugins will be installed automatically in your browser. But you have a control over them.

I need to test Unity3D Web Player. But there is a problem – the checksum of Unity3D has recently changed, and you have to update the checksums first:

poganin@linux-7tpy:~> sudo pipelight-plugin –update

Now, clear the plugin cache of your browser to be sure you will have no previous errors:

poganin@linux-7tpy:~> sudo pipelight-plugin –create-mozilla-plugins

Now, you are ready to install Unity3D Web Player plugin. Remember, you have to restart the browser to make the plugin work after enabling and to make the plugin clear out  after disabling.

To enable one of the plugins, run:

pipelight-plugin –enable the_plugin_name

for example:

poganin@linux-7tpy:~> sudo pipelight-plugin –enable unity3d

root’s password:

The following modules require a license confirmation before they can be enabled:

[*] Unity Web Player

By continuing the installation you agree that you’ve read and accepted the Web Player License Agreement:

Do you accept the 1 license(s) above? [Y/N] y

Plugin unity3d is now enabled


To disable one of the plugins, run:

pipelight-plugin –disable the_plugin_name

for example:

poganin@linux-7tpy:~> sudo pipelight-plugin –disable unity3d

root’s password:

Plugin unity3d is now disabled

I hope you will be successful. Just try it out.

For people who use Pipelight (unity3D plugin) – Unity3D Web Player is often updated, and its checksum is changed. That’s why, you need to run a few commands every time. It’s really irritating. So I wrote the script. Copy it and paste to a new text file. Call it Pieplight. This file should be placed in your bin directory so that it can be on PATH. After Unity3D having updated, just run Pipelight in your console. All these commands will run, and Unity3D Web Player will be updated and running.


    #FDS-Team: Pipelight Project
    #Tomasz Zackiewicz, Pipelight.sh

    #update the checksum of Unity3D Web Player
    sudo pipelight-plugin --update
    #clear the plugin cache for Firefox
    sudo pipelight-plugin --create-mozilla-plugins
    #enabling Unity3D Web Player
    sudo pipelight-plugin --enable unity3d

It’s for Firefox; for other browsers, you probably shouldn’t use this command:

sudo pipelight-plugin –create-mozilla-plugins

Enjoy Unity3D games!
