ERROR - FF client tests django 1.8 

After I installed django 1.8 and run the harvest command in shell I get this:

``` python
ERROR: Failure: WebDriverException (Message: Can't load the profile. Profile Dir: %s If you specified a log_file in the FirefoxBinary constructor, check it for details.
)

```

usually what happens was that the test ran perfect now it just makes the FF browser comeup but nothing happens.

*using FF v.43
