New Selenium Marionette connections will no longer be accepted

When I run my java program, I get this error message:

1494797744010   geckodriver INFO    Listening on 127.0.0.1:5968
1494797744672   geckodriver::marionette INFO    Starting browser \\?\C:\Program Files\Mozilla Firefox\firefox.exe with args ["-marionette"]

Some new errors appear while the program is running:

JavaScript error: resource://gre/modules/FileUtils.jsm, line 70: NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFile.create]

Eventually I get this information and the program stops working:

1494798016809   Marionette  INFO    New connections will no longer be accepted

What could be causing this error and how can I fix it? I am using Firefox 53.0.2 and geckodriver 0.16.1

Here is the answer to your question:

  • The first set of errors you see as 1494797744951 addons.manager ERROR startup failed: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE)

    is that you haven't configured the geckodriver to suppress / ignore these errors in the console. But they are harmless, and if not ignored / suppressed, you should live well with them.

  • The second set of errors that you see JavaScript error: resource://gre/modules/FileUtils.jsm

    are JavaScript errors, which again reflect that you haven't configured the geckodriver properly to ignore or suppress JavaScript errors appearing in the console. Again, they are harmless, and if not ignored / suppressed, you should live well with them.

  • The last set of errors you see New connections will no longer be accepted

    is something serious Marionette

    , complaining, which essentially means that you are trying to execute a test step that geckodriver cannot reach. Hence, you may need to change your geckodriver code to accomplish this task.



Let me know if this answers your question.
