FF 26 and Se 2.39.0 not compatible

[Rick Simpson]

Hi,

Fired up my automation for the first time since the holidays and discovered I couldn't get it run.  I did some digging around and discovered FF had upgraded to v26.  Did some more googling and found posts claiming that Se 2.39.0 fixed the problem.  I upgrade to 2.39.0 and the problem changed slightly but still had the same basic problem.  What I found upgrading to FF 26 was a failure trying to start the NewProfileExtensionConnection:

FAILED: blah
org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(/Applications/Firefox.app/Contents/MacOS/firefox-bin) on port 7055; process output follows:
*** LOG addons.manager: Application has been upgrade
*** LOG addons.xpi: startup
…

...

After upgrading to 2.39.0, it appears to get a little further but still fails in the NewProfileExtensionConnection:

FAILED: blah
java.lang.NoClassDefFoundError: com/google/common/base/Optional

...

Is this a known issue? Is there a workaround outside of downgrading FF and Se?

Thanks

Hi!

I had the same problem with the same setup. I added the dependency com.google.guava:guava:16.0 to my project and the errors went away! Don't know if you are using maven, but if so add the following dependency:

<dependency>
 <groupId>com.google.guava</groupId>
 <artifactId>guava</artifactId>
 <version>16.0</version>
 <scope>test</scope>
</dependency>
