Which Firefox version is compatible with Selenium 2.53.0? I tried Firefox 45.0 and I am getting this exception:

org.openqa.selenium.WebDriverException: Failed to connect to binary           

FirefoxBinary(/Applications/Firefox.app/Contents/MacOS/firefox-bin) on   port 7055; process output follows:

I have had a similar issue while running Selenium Webdriver 2.53.0 with Firefox 47.0. For me, downgrading the Firefox version from Firefox 47.0 to Firefox 46.0 worked decently well. You can try downgrading your Firefox version and it would work fine with Selenium Webdriver 2.53.0
