The Shotgun Browser Plugin (Beta)

This is a browser plugin that is an extension for the Shotgun production tracking system. It implements the local file integration and pipeline integration features of Shotgun.

Note that the plugin is being replaced by functionality provided by Shotgun's Desktop application. The newer implementation works for browsers that have removed support for NPAPI plugins like Chrome. For more details click here.

Table of Contents


This plugin replaces Shotgun's previous implementations of local file linking and pipeline integration. The previous implementation was based on a Java applet, and due to the various security issues surrounding Java we wrote this native plugin. It uses the firebreath library as a foundation and has been written with security in mind.

Supported Browsers

This plugin is supported for all browsers the Shotgun supports. The detailed list is here, but most versions of Safari, Chrome, and Firefox should work.

Note: Chrome does not support CentOS 6, and there are solutions for getting it working that use an alternate libc, which will crash the plugin. A working Chrome RPM can be found here. See issue #7 for the gory details.

Supported Platforms

This plugin is supported on OSX (10.6+), Windows (XP+), and Linux.


Without any customization, this plugin only exposes its functionality to web pages on hosted shotgun sites. The methods it implements will not be available except for pages served from over https.

If you run a local installation of shotgun, you can set two environment variables to override this default security:

  • SHOTGUN_PLUGIN_PROTOCOL_RESTRICTION - The protocol portion of a url must match this. Defaults to "https".
  • SHOTGUN_PLUGIN_DOMAIN_RESTRICTION - The host portion of a url must match this. Defaults to "*"

These environment variables can contain wildcards to match multiple values. SHOTGUN_PLUGIN_DOMAIN_RESTRICTION can be a comma separated set of wildcarded domains to match.

Example - Configuring the browser plugin for a local Shotgun server

If you using the browser plugin with a hosted Shotgun installation (e.g. your Shotgun url ends with, things should work out of the box using the browser plugin's default settings. However, if you are using the browser plugin with a locally installed shotgun client, things will not work out of the box. You need to tell the browser plugin which urls you use for your internal site.

Here's an example how to set things up when using a local Shotgun. Imagine your shotgun site can be reached using the following addresses:

  • http://shotgun

We then need to set the following two environment variables:


Environment variables are set differently on different operating systems. On Linux, they are typically added to a login script. On windows, they can be modified using the control panel and on Macosx they are typically added to a special configuration file (/etc/launchd.conf).


Installing on OSX

A pre-built binary is available here.

Double clicking on the dmg will bring up this window:


Simply drag the plugin into the linked folder and restart your browser to enable the plugin. The folder is /Library/Internet Plug-Ins/, which will install the plugin for all users. If you do not have administrative privledges or want to install the plugin only for yourself, you can copy the plugin to ~/Library/Internet Plug-Ins/ instead.

Installing on Windows

A pre-built binary is available here.

Double clicking on the installer will bring up a standard installer window:


If you manage an environment that does not support distribution via the installer, you can use regsvr32 and this dll as an alternative.

Installing on Linux

A pre-built binary is available here. For it to run you need to have libgtk2 installed.

This binary was built on CentOS 6.3 and has fairly minimal library dependencies (libgtk2). There is a good chance it will work on any Linux system based on a 2.6 kernel. To install it copy the binary to /usr/lib64/mozilla/plugins or ~/.mozilla/plugins.

Your install location may differ depending on your linux flavor and system architecture.

Note that on CentOS 7, SELinux is configured to be more restrictive by default and blocks the plugin's access to the files system. If you are running Gnome 3, you should see a notification about this when trying to use the plugin. You will need to add an exception for the plugin to run correctly.

Verifying Installation

Once the plugin is installed and you have restarted your browser, you should see the plugin listed in the browser plugin list. For example, in Chrome you will see a plugin named "Shotgun Integration":


In addition, in the javascript console when visiting a Shotgun page where local file linking or pipeline integration is turned on, you should see a message like the following:


If you do not see that message, then the plugin is not working.

If you see the message, but instead of reading "Protected Security Scope" it reads "Public Security Scope", then you need to update your environment to activate the plugin. See the section on security above for instructions on how to do this.

Launching via a Wrapper

By default the browser will use the operating system default to launch a command (the equivalent of xdg-open on linux, open on osx, and run on windows). If you wish to provide your own wrapper for launching files you can set the SHOTGUN_PLUGIN_LAUNCHER environment variable to point to your custom wrapper. If that is set, then the wrapper will be called with the path as its only argument.


The firebreath build instructions are very thorough. You should be able to build this plugin by following those instructions.

Building on OSX

This plugin has been built on OSX 10.6, 10.7, and 10.8. Firebreath's DMG creation functionality is currently experimental, but functions well. The one issue with it is that rebuilding the source will raise an error at the DMG generation if the previous DMG has not been deleted or moved aside.

Building on Windows

This plugin has been built on Windows XP and Windows 7 using Visual Studio Express 2012. The extra functionality for creating an MSI installer has been turned on, which requires WiX to be installed. The firebreath instructions on how to build for Windows has detailed instructions on how to install these dependencies.

Building on Linux

Building on Linux if fairly simple. There is a bug with firebreath where the script which generates the Makefiles needs to be run twice to correctly generate a build directory. The only package dependency for building should be on libgtk2.

v0.0.5 - 2014 May 19

  • fixed: The plug-in no longer hangs when launching various Applications using Toolkit. This problem was previously affecting 3ds Max & Hiero under certain conditions as well as custom wrapper scripts that output large amounts of debug during execution
  • fixed: Files containing non-ascii characters are now supported correctly when using local file linking. Previously these could cause instability when linked/opened.
