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:
foreignInstall":false,"hasBinaryComponents":false,"strictCompatibility":false,"l ocales":[],"targetApplications":[{"id":"{ec8030f7-c20a-464f-9b0e-13a3a9e97384}","minVersion":"45.0","maxVersion":"45.*"},{"id":"xpcshell@tests.mozilla.org","minVersion":"0","maxVersion":"10"}],"targetPlatforms":[],"multiprocessCompatible":false,"seen":true}
I had the similar problem running Selenium Webdriver 2.53.0 with Firefox 47.0.
Selenium Webdriver 2.53.0 works with Firefox 46.0. You can find the the mentioned version at https://support.mozilla.org/en-US/kb/install-older-version-of-firefox.
Also you could try to add:
System.setProperty("webdriver.firefox.bin","C:\\Users\\AppData\\Local\\Mozilla Firefox\\firefox.exe");
WebDriver driver=new FirefoxDriver();
if it is also not working, then you need to downgrade your FF
hi I had the same problem, I hope you have solved yours, but maybe my answer can help someone else.
i found firefox 26, selenium 2.48.2 and a webdriver that work very good together. here are the download links:
