WebDriverException... moveto did not match a known command

Question

When the Mouse Over Keyword is called I get the following error :

WebDriverException: Message :POST /session/bcb99bc5-1b47-4438-b1b7-471785ea34c8/moveto did not match a known command on Mozilla FireFox(geckodriver)

Answer 1

Sadly this appears to be a bug in the Mozilla/geckodriver side of the Actions implementation that has been lingering since mid 2016. If you really need this, switch to something not Firefox or grab a pre-geckodriver Firefox (47 or below, I believe) and use the older webdriver bindings (i.e., Selenium 2). Unfortunately, it is not as easy as just getting the older FF version.
