python - Browsing context has been discarded using GeckoDriver Firefox through Selenium

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:

Browsing context has been discarded Failed to decode response from marionette

Any idea what could have caused this outside the code? (since no changes were made)

I'm using firefox and geckodriver. After i got these errors i updated firefox, geckodriver, and selenium, but it didn't help.

This error message...

Browsing context has been discarded
.
Failed to decode response from marionette

...implies that the communication between GeckoDriver and Marionette was broken.

Some more information regarding the binary version interms of:

  • Selenium Server/Client
  • GeckoDriver
  • Firefox

Additionally, your code block and the error stack trace would have given us some clues about whats wrong happening. However this issue can happen due to multiple factors as follows:
