Acquiring the console log data from Firefox version 43 using Selenium, all without the use of any

Can Selenium retrieve the console.log from browsers like Firefox 43? If so, how can it be done?

My settings are as follows:

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
LoggingPreferences logs = new LoggingPreferences();
logs.enable(LogType.BROWSER, Level.ALL);
logs.enable(LogType.DRIVER, Level.ALL);
logs.enable(LogType.CLIENT, Level.ALL);
logs.enable(LogType.PERFORMANCE, Level.ALL);
logs.enable(LogType.PROFILER, Level.ALL);
logs.enable(LogType.SERVER, Level.ALL);
capabilities.setCapability(CapabilityType.LOGGING_PREFS, logs);

FirefoxBinary binary = new FirefoxBinary(new File(...));
FirefoxProfile profile = new FirefoxProfile();
WebDriver driver = new FirefoxDriver(binary, profile, capabilities);

//...performing actions with the driver ...

driver.manage().logs().get(LogType.BROWSER) // tried every LogType

The current output I receive looks something like this:

1450878255029   addons.xpi  DEBUG   startup
...
Error in parsing value for 'display'.  Declaration dropped.

However, I am not able to see the output that is written in the browser's JavaScript console log.

I have experimented with various Firefox profile settings such as:

profile.setPreference("extensions.sdk.console.logLevel", "all");
profile.setPreference("webdriver.log.file",tempfile.getAbsolutePath());
profile.setPreference("webdriver.firefox.logfile", othertempfile.getAbsolutePath());
profile.setPreference("webdriver.log.driver", "ALL");

Unfortunately, none of these attempts have helped solve the issue. The same process works perfectly fine with Chrome.

Dealing with the same issue, I found myself inundated with excessive log noise regarding CSS, security, and network matters, but lacking the actual logs generated by the application using console.log. Despite using identical versions of WebDriver and Firefox as you, this issue did not present itself with other browsers.

To address this, I took it upon myself to enhance my client code with a custom log recording solution. In terms of wire protocol communication:

Utilize execute to incorporate the following script into the client:

window.recordedLogs = [];

console.log = function (message) {

    if (typeof message === 'object') {
        message = JSON.stringify(message);
    }

    window.recordedLogs.push(message);
};

Use execute to retrieve window.recordedLogs

Caution: The provided code is rudimentary and does not account for handling multiple messages passed to the log method or other logging functions such as info, error, etc.

Nevertheless, it serves as a viable cross-browser alternative to the wire protocol's log method.
