I keep running into this error when using a tool that attempts to load a locally-saved web page via Selenium, gekodriver, and firefox. Versions utilized:
- Selenium: 3.0.1
- Gekodriver: 13.0
- Firefox: 46.0
My constraints are that I have to use selenium 3.0.1, but the other dependencies can be altered. Has anybody run into this issue before?

As per the geckodriver specifications Selenium users must update to version 3.11 or later to use geckodriver like other clients that follow the W3C WebDriver specification and are also supported.
Additionally, support for GeckoDriver is best in Firefox 57 and greater, however the more recent the Firefox version, the better the experience as they contain more bug fixes and the recent features while some features will only be available in the latest Firefox Nightly with GeckoDriver.
This usecase
If you are working with the legacy Firefox releases (i.e. till Firefox 47.x) geckodriver still works but you have to explicitly set the property "marionette" to false as follows:
cap = DesiredCapabilities().FIREFOX
cap["marionette"] = False
