Steps to reproduce -

    DesiredCapabilities cap = DesiredCapabilities.firefox();
    cap.setCapability("marionette", false);
    cap.setCapability("firefox_profile", new ProfilesIni().getProfile("default"));

    FirefoxDriver driver = new FirefoxDriver(cap);
    driver.get("https://www.google.com/");

This is a java problem, not a selenium problem. Configure your JVM settings.

@lukeis I think problem is not in JVM settings. If I use selenium 2.53.1 - everything works as expected. I tried to run with settings -Xms512m -Xmx512m and got the same error.

Able to replicate the issue with following steps-

                DesiredCapabilities capabilities = DesiredCapabilities.firefox();

                ProfilesIni profile = new ProfilesIni();
                FirefoxProfile firefoxProfile = profile
                        .getProfile("default");
                capabilities.setCapability("marionette", false);
                capabilities.setCapability(FirefoxDriver.PROFILE,
                        firefoxProfile);

                driver = new FirefoxDriver(capabilities);

And trace as follows-

I reproduced this issue using 3.0.1 trying to run remotely with an 18MB local Firefox profile folder, on Mac OS X.

I specified various heap sizes, such as -Xmx1024m and -Xmx2056m and even -Xmx8192m, but the error persisted.

I fixed my problem by reducing the Firefox profile folder from 18MB to 13MB by deleting all sub-folders inside it and leaving all top-level files. The test now runs even with the default JVM heap settings.

Perhaps the issue is related to some particular sub-folders inside the profile directory itself.

Hello everyone,

I can not find how to reduce Firefox profile folder

Best regards
