FireEyes Stand-Alone Version Quickstart Guide

The stand-alone version of FireEyes is an extension to the Firefox web browser that is provided free of charge with a limited-use license by Deque Systems. It is provided for individual, non-commercial use by developers and QA testers to check pages for accessibility issues, then use the integrated remediation advice to solve them. As an add-on extension, FireEyes Standalone adds a new tab on the Firebug tab bar with the ability to analyze a web site for WCAG 2.0 Level A and AA and Section 508 accessibility violations. Users of this version have the ability to download reports, and share accessibility policy settings with other FireEyes users.

To quickly start using FireEyes standalone, follow the instructions below. Prior to installing and using this version of FireEyes, you must first install an older version of the Firefox web browser that supports it, then secondly install the Firebug extension for Firefox that is required for integration with FireEyes.

Step 1: Download and Install the Firefox Extended Support Release (ESR) browser

  1. Download Firefox Extended Support Release (ESR).
    • Direct link for English (US) Windows: Download
    • Direct link for English (US) Mac: Download
  2. From the download location, double-click the setup file (for example, 'Firefox Setup 38.5.2esr.exe') to run the installation program.
  3. On the Welcome Wizard dialog box, click the Next button to continue.
  4. Important Note:

    In order to have two different installed versions of the Firefox browser on your computer, you must install the ESR version in a different Program Files folder than the existing, newer version. To specify a non-default installation location folder, you must first select the Custom Setup Type.

  5. On the Setup Type dialog box, select the Custom radio button option, then click the Next button.
  6. On the Choose Install Location dialog box, in the Destination Folder field, specify the desired folder location. Either type the path, or use the Browse and Make New Folder buttons as necessary. Be sure the location is different than the previously-installed, current (newer) Firefox version. Then click the Next button.
  7. On the Set Up Optional Components dialog box, leave the Install Maintenance Service box checked, then click Next.
  8. Select icon options as desired, then click Next.
  9. On the Summary dialog box, click the Install button, then when prompted, click the Finish button to close the installation wizard dialog box.
  10. You can only run one version of Firefox at one time, so if you have the newer, non-ESR version open already, you will not be able to launch the ESR version until you exit.

Step 2: Install the FireBug extension as an add-on to the Firefox browser.

Firebug is a free, open-source Firefox development tools extension that integrates with FireEyes to provide enhanced accessibility tools to go along with its HTML, CSS and Javascript editing, debugging and monitoring tools. Prior to installation, it is recommended that you first review the Compatibility table listing the version numbers that are compatible with each version of Firefox to ensure you install a version that is compatible with the version of Firefox you are using.

Due to a known issue with Firebug v.3 alpha, we recommend you NOT install that version. Before you begin, in the event you have two versions of the Firefox browser installed on your local computer, be sure you are using the ESR version of Firefox 31 - 38 (ESR), and not a more modern version (39 or later) to search for and install Firebug.

  1. In Firefox ESR, navigate to the Add-ons Manager page (Tools > Add-ons or [Ctrl]+[Shift]+[A]).
  2. In the Search field, type 'Firebug', then press [Enter].
  3. In the Available Add-ons search result tab, to the right of the Firebug, click the Install button.
  4. Alternately, you can install Firebug from the project's release page or source code if desired.

Step 3: Register for, download, and install standalone FireEyes.

Registration to use FireEyes is requested but not required.

  1. Go to
  2. Optionally, enter your Name, Email Address, and Company Name in the form.
  3. Click the Register button. Note: You agree to the license by clicking the Register button.
  4. In the confirmation dialog box, click the OK button to accept the license agreement and download the 'FireEyesStandalone.xpi' file.
  5. On the Add-ons Manager page (about:addons) in Firefox, click the gear icon drop-down menu, then select the Install Add-on From File option.
  6. Browse for and select the .xpi file, click Open, then Install Now.
  7. Restart Firefox ESR after the installation completes.
  8. Open Firebug from the Tools menu. You will see the FireEyes option in Firebug.
  9. Review your settings under the FireEyes settings tab.
  10. Select NOW on the current document tab to analyze the current page in the browser.
