Actual behaviour:

Firefox is finished with crash.

The two stack traces differ quite a lot. The first one seems to be from the java side of things, but this last one appears to be someone calling geckodriver's (non-existent) shutdown handler.

Are you using geckodriver directly? The selenium-standalone server? Grid?

[daniilmeranov]

I use selenium-server-standalone-3.5.3.jar
Hub: java.exe -jar "%TestTools%\Selenium\selenium-server-standalone-3.5.3.jar" -role hub
Node: java.exe -jar "%TestTools%\Selenium\selenium-server-standalone-3.5.3.jar" -role node -hub http://localhost:4444/grid/register

HubUrl from app.config contains: "http://localhost:5555/wd/hub"
geckodriver.exe located in available folder (included to path)

[daniilmeranov]

I updated testcase block with full source code I ran.
Project is used following packages from NuGet:

  <package id="Selenium.Support" version="3.5.2" targetFramework="net462" />
  <package id="Selenium.WebDriver" version="3.5.2" targetFramework="net462" />

[barancev]

Can you retest with a newer Firefox version, e.g. Developer Edition?
https://www.mozilla.org/firefox/developer/

[daniilmeranov]

Yes, Dev Edition (56.0b11) works stable. Thank you! Is it Firefox 55 kernel issue?

[barancev]

Yes, seems to be a browser issue.
