Deque FireEyes accessibility testing plugin

I’ve done a lot of accessibility testing and development work over my career. One of the many free tools that I use in that role is FireEyes. Deque also has some commercial packages for developer use.

FireEyes adds a new tab on the Firebug tab bar and adds the ability to analyze a web site for WCAG 2.0 Level A and AA and Section 508 accessibility violations. The Stand-Alone version of FireEyes is a browser plugin to the FireFox browser. It requires that the FireBug plugin already be installed


  • Firefox 31-41

    As of 2015aug21, the current version of the extension is NOT signed and will not execute on later versions. [See my later post on this topic]

  • FireBug 2.x – Do NOT install Firebug v3 alpha as the tab will not show.

NOTE: should be on Firebug tab labeled “Worldspace Fireyes”, but does not seem to be available in Firebug3.

NOTE: if you try to download in MSIE, you must rename the .zip to .xpi, and then open with Firefox.


Selenium Firefox modifyheaders

A few of my tests require access to modify the HTTP Request headers. Unfortunately, Selenium hides access to them to allow for portability, and to better emulate what “users” generally can change. To work around this a Firefox extension can be used and configured at runtime for this purpose.

NOTE: for Maven, you need to place a copy of the .xpi file referenced into the /src/test/resources folder for Selenium to locate it.

In the example below, I’m setting the HTTP Header for “DNT” to “1”.

public FirefoxDriver createFirefoxDriver() throws URISyntaxException, IOException {
// Specify the install location (if not default)
// Prevent Console log "noise" from the Selenium Firefox plugin
System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.SimpleLog");
System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", "OFF");
System.setProperty("", "OFF");

final FirefoxProfile profile = new FirefoxProfile();
final URL url = this.getClass().getResource("/modify_headers-");
final File modifyHeaders = modifyHeaders = new File(url.toURI());


profile.setPreference("modifyheaders.headers.count", 1);
profile.setPreference("modifyheaders.headers.action0", "Add");
profile.setPreference("modifyheaders.headers.name0", "DNT");
profile.setPreference("modifyheaders.headers.value0", "1");
profile.setPreference("modifyheaders.headers.enabled0", true);
profile.setPreference("", true);
profile.setPreference("modifyheaders.config.alwaysOn", true);

final DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
return new FirefoxDriver(capabilities);
