Hi,

java.lang.UnsupportedClassVersionError happens because of a higher JDK during compile time and lower JDK during runtime.


Testing experts always check below configurations for this type of issue:
a) Go to Eclipse. Open the Project -> Properties -> Java Compiler

b) Enable project specific settings

c) Then select Compiler Compliance Level to 1.6 or 1.5, build and test your app

Hope this solution resolves your issue.

Thanks

Your code was compiled with a different Java Version (higher  maybe 1.8) and executed in lower ( say 1.7 ).

Try re -compiling your code in lower Java version .

Thanks

Use chrome drive best solution.

need to make small changes.

1- Download chrome driver and then 

a) Give the path to chrome driver and use chrome drive rather the firefox driver.
