selenium: Unable to connect to host 127.0.0.1 on port 7056 / Selenium 2.53 with ff 45.0

Meta -

OS: Selenium Version: Browser: Browser Version:

After upgrading from 2.45 jar to 2.53 and ff37 to ff45 I’m getting this error. Please give me a feedback asap. I`ve tried 2.52 and ff44 - same issue was raised Tests are trigger by a jenkins job, if matters.

Expected Behavior - Firefox should start without problems

Actual Behavior - Error from summary is thrown

`Caused by: org.openqa.selenium.remote.ErrorHandler$UnknownServerException: Unable to connect to host 127.0.0.1 on port 7056 after 45000 ms. Firefox console output:

Here is also my firefox profile: `private FirefoxProfile getFirefoxProfileSettings() {

    FirefoxProfile firefoxProfile = new FirefoxProfile();
    firefoxProfile.setPreference("browser.download.folderList", 2);
    firefoxProfile.setPreference("browser.download.manager.showWhenStarting", false);
    firefoxProfile.setPreference("browser.download.dir",<validPath>);   
    firefoxProfile.setPreference("plugin.disable_full_page_plugin_for_types", "application/pdf,application/vnd.fdf");
    firefoxProfile.setPreference("browser.helperApps.alwaysAsk.force", false);
    firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/excel,application/vnd.ms-excel,application/x-excel,application/x-msexcel,application/pdf);
    firefoxProfile.setPreference("pdfjs.disabled", true);
    firefoxProfile.setEnableNativeEvents(false);
    firefoxProfile.setPreference("dom.max_script_run_time", 0);
    firefoxProfile.setPreference("dom.max_chrome_script_run_time", 0);
    return firefoxProfile;

}
