title: Browsing context has been discarded using GeckoDriver Firefox through Selenium
body: <p>I didn't make any changes to my python selenium program and it worked fine 3 days ago.  Now when i try to use it i get:</p>
  
  <p>Browsing context has been discarded
  Failed to decode response from marionette</p>
  
  <p>Any idea what could have caused this outside the code? (since no changes were made)</p>
  
  <p>I'm using firefox and geckodriver. After i got these errors i updated firefox, geckodriver, and selenium, but it didn't help.</p>
