In java, you can reproduce adding this in the capabilities:

JsonObject options = new JsonObject();
JsonObject log = new JsonObject();
log.addProperty("level", "trace");
options.add("log", log);
capabilities.setCapability("moz:firefoxOptions", options);
Caused by: org.openqa.selenium.WebDriverException: Firefox option was set, but is not a FirefoxOption: {log={level=trace}}

I think this originates from the Java side. There are no such checks in the Python bindings.

andreastt commented

Selenium shouldn’t have to validate the correctness of the moz:firefoxOptions dictionary. The only authoritative checks for that can be done in geckodriver.

Is there a workaround for this at present other than rolling back to a beta release of the JS lib? I have written code dependent on a feature added in 3.0.0+ to the JS lib for disabling the promise manager and just found out I can't use the firefox driver without this error popping up.

Reproduced issues with

Firefox 51.0.1
Selenium jar : 3.0.1 and 3.0

after downgrading selenium to 3.0.0-beta-4 works.

@shs96c do you have any idea? You seems to be the man behind the check (fdd21f9)

minusnine commented

This is fixed in Selenium 3.3.1 with commit bc4c207.

This is still reproducible:
Selenium v3.4.0 (Java bindings)
Firefox: v52.0.2 & v53.0
GeckoDriver: v0.16.0

DesiredCapabilities dc = DesiredCapabilities.firefox();
dc.setCapability("moz:firefoxOptions", new JsonParser().parse("{log: {level: trace}}"));
FirefoxDriver firefoxDriver = new FirefoxDriver(dc);
