问题
I want to run a Python 3 script on my Raspberry Pi and do stuff with it. The script works just fine on my Mac, however I want it to run 24/7 and the Pi is more energy efficient. Not to mention I need my Mac for other things.
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
browser = webdriver.Firefox()
browser.get('www.website.com')
I am running Raspbian Jesse and have installed Iceweasel (installed today through command line, V 45) and geckodriver (0.18.0).
Running the script throws the following error:
selenium.common.exceptions.WebDriverException: Message: Unable to find a matching set of capabilities
Ideas?
Cheers.

I ran into the exact same problem. For me, installing an older version of selenium fixed the problem.
sudo pip3 uninstall selenium
sudo pip3 install selenium==3.3.2
Works for me on Raspbian Jessie with Firefox 45.9.0, geckodriver v0.18.0.

Try updating to the latest Selenium, Firefox, and geckodriver.
Firefox:
sudo apt-get install firefox-esr --upgrade
Selenium:
pip install selenium --upgrade
Mozilla no longer publishes arm7 geckodriver binaries, but there are instructions to crosscompile it for arm7 from another platform here and regular building instructions here. The first step is downloading the source:
curl https://hg.mozilla.org/mozilla-central/archive/tip.zip/testing/ > testing.zip
unzip testing.zip
Or if v26 is sufficient, I've compiled it for arm7 here: https://github.com/Tahlor/geckodriver
