** If any of the above are missing we will have to unfortunately close your issue. We will gladly reopen the issue once all the information requested has been added **

@raviautomation09 Can you please try use the latest nightly. I think this issue might have already been fixed but want to check.

If it still fails can you add the verbose log from GeckoDriver. You may need to look up in your driver bindings how to do that.

@raviautomation09 If you can't test this out by Monday next week (22 May) I will unfortunately need to close this issue.

The issue still persist after executing on Nightly. Below is the logs when driver.close() and driver.quit() is called:

@raviautomation09 Are you calling close and then quit? Its near impossible to solve this issue when you are only giving snippets of the log. We can't see what is happening around which could solve this problem.

Please give a full snippet, from session create to after the errors have happened. If we do not get the full log unfortunately we will need to close this issue as won't fix.

Do you run driver.quit() after driver.close()? If yes this will not work given that the close() command already closed the last window of Firefox, and as such the application already shutdown. So calling quit() afterward doesn't make sense.

Also I can see the following in the log for quit(): GET /shutdown did not match a known command. Is this a problem with your binding? It's not clear which one and which version you are using. So please report those details.

We should probably not return a 500 Internal Server Error when driver.quit() is called after a driver.close() implicitly ends the session.

The specification’s definition of the Delete Session command is:

1. Try to close the session.
2. Return success with data null.

You could interpret this the way geckodriver currently does, and return an error from step 1 because there is no Marionette connection (internal error), or you could try to end the session and if there is no session, return success anyway.

I think probably a specification clarification is needed here. For compatibility with other WebDriver implementations I think there should be a step 0 in Delete Session that returns immediately if there is no active session.

@AutomatedTester What do you think?

@AutomatedTester mind giving us some feedback about the proposal from @andreastt ?

we should do

I think probably a specification clarification is needed here. For compatibility with other WebDriver implementations I think there should be a step 0 in Delete Session that returns immediately if there is no active session.

I submitted https://github.com/w3c/webdriver/pull/926 to the specification.

For geckodriver we track the work in https://bugzilla.mozilla.org/show_bug.cgi?id=1403510.

Also I can see the following in the log for quit(): GET /shutdown did not match a known command. Is this a problem with your binding? It's not clear which one and which version you are using. So please report those details.

Thank you it helps me to solve my problem running tests on Firefox driver

Hello, I am using geckodriver 0.24 and firefox and I encountered the same original issue (which is closed now,so that is why I made the comment here ) https://github.com/mozilla/geckodriver/issues/1512 But with a major difference. The steps to generate the error didn't include delete session and this issue can't be reproduced always. This is the log: Failed to click element id=main-action-create after retrying 5 times with error Message: Tried to run command without establishing a connection Teardown:

@sofiand-png so why are you adding the comment on this issue then? If it's not related please file a new issue. Thanks.

Because you set the original ticket as a duplicate of this one (although I don't see that clearly), so they should have the same root cause according to you. Isn't it ?

Again, this issue is about the "Delete Session" command and not anything else.

5 years on, and still no real solution to this problem?!
