Python Selenium doesn't load firebug extension (firefox)

[fike]

Hi,

The Python-Selenium doesn't load firebug extension of Firefox, which happen in the Firebug versions superior the 2.0.7. This doesn't happen in the Firebug 1.XX.XX versions, I think that the problem is file format changed.

Firebug 1.XX.XX version

fike@kamino:~/d/annabe/annabe$ file firebug-1.13.0a10.xpi 
firebug-1.13.0a10.xpi: Zip archive data, at least v1.0 to extract

Firebug 2.XX.XX version

fike@kamino:~/d/annabe/annabe$ file firebug-2.0.11-fx.xpi 
firebug-2.0.11-fx.xpi: Zip archive data, at least v2.0 to extract

Below a example code, it's same of Python-Selenium FAQ.

Code example:

Python 2.7.10 (default, Jul  1 2015, 10:54:53) 
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from selenium import webdriver
>>> 
>>> fp = webdriver.FirefoxProfile()
>>> 
>>> fp.add_extension(extension='firebug-2.0.11-fx.xpi')
Traceback (most recent call last):
  File "/usr/local/bin/firefox_navigate.py", line 19, in <module>
    fp.add_extension(extension='firebug-2.0.11-fx.xpi');
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_profile.py", line 93, in add_extension
    self._install_extension(extension)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/firefox_profile.py", line 264, in _install_extension
    with open(os.path.join(tmpdir, name), 'wb') as f:
