IEDriverServer设置后，WebDriver Firefox配置文件不起作用

Question

I've been using webdriver.Firefox() for my test cases, but wanted to test on IE. I downloaded IEDriverServer, added it to my PATH and ran the IE test case successfully. However, when I then tried switching back to Firefox and running the same test case, the Firefox browser opened up, but nothing happened, and then I received this error:

I've removed the PATH to IEDriverSetup and went so far as to remove it. I restarted Eclipse (I'm using it to run my Python/WebDriver tests) and restarted IE and Firefox to no avail.

Any help is appreciated.

EDIT

I am using Python 3.3 to develop my test cases, if that makes a difference.

Answer 1

Is there a __ pycache __ directory among your files? I removed it. No error once it is removed.

PS. python 3.3.2
