FireFox Profile Error - firefox

Question

I am getting this https://www.mozilla.org/en-US/firefox/43.0.1/firstrun/learnmore/ while running my script in Firefox. This was running just fine until last week but it has stopped working now. I renamed and deleted the Firefox profile but that didn't help. Here are the error I am receiving in Eclipse. Any help will be appreciated.
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

This issue seems fixed in recent versions of FirefoxDriver. If you are not using latest version of FirefoxDriver, please upgrade it to 2.49.1 (latest version)
