Selenium does not work with Firefox 12.0

Question

Selenium does not work after upgrading Firefox to the latest version 12.0. It does not work with the message below. Please advise, it still works fine if I use an older version of firefox.

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output: *** LOG addons.xpi: startup *** LOG addons.xpi: Skipping unavailable install location app-system-local *** LOG addons.xpi: Skipping unavailable install location app-system-share *** LOG addons.xpi: Ignoring file entry whose name is not a valid add-on ID: C:\Users\Abdul\AppData\Local\Temp\anonymous869859993705622974webdriver-profile\extensions\webdriver-staging *** LOG addons.xpi: checkForChanges *** LOG addons.xpi: No changes found at org.openqa.selenium.firefox.internal.NewProfileExtensionConnection.start(NewProfileExtensionConnection.java:95) at org.openqa.selenium.firefox.FirefoxDriver.startClient(FirefoxDriver.java:157) at org.openqa.selenium.remote.RemoteWebDriver.<init>(RemoteWebDriver.java:93) at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:136) at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:78) at Google.Open_Google_Firefox.Test_Google_FireFox(Open_Google_Firefox.java:13) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:80) at org.testng.internal.Invoker.invokeMethod(Invoker.java:702) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:894) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1219) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:127) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:111) at org.testng.TestRunner.privateRun(TestRunner.java:768) at org.testng.TestRunner.run(TestRunner.java:617) at org.testng.SuiteRunner.runTest(SuiteRunner.java:334) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:329) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:291) at org.testng.SuiteRunner.run(SuiteRunner.java:240) at org.testng.SuiteRunnerWorker.runSuite(SuiteRunnerWorker.java:53) at org.testng.SuiteRunnerWorker.run(SuiteRunnerWorker.java:87) at org.testng.TestNG.runSuitesSequentially(TestNG.java:1185) at org.testng.TestNG.runSuitesLocally(TestNG.java:1110) at org.testng.TestNG.run(TestNG.java:1022) at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:109) at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:202) at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:173) FAILED CONFIGURATION: @AfterMethod tearDown

Answer 1

I had the same error since 2.16. Updating to 2.21.2 allowed me to use Firefox 12.

Answer 2

Removing the current version and reinstalling the previous version of Firefox solves this problem.

This is because the latest version of Firefox is not integrated with the current version of Selenium.

Answer 3

And if you return to Firefox 11? (or lower?)

If you go back and this is still a problem, look at the Selenium website and report it as an error. If this is really a mistake, I would not be too surprised if others also reported it.
