"Firefox webdriver could not be verified for use in Firefox and has been disabled"
<p>Since Firefox updated to version 43, I get the following message when trying to run an application using Webdriver: "Firefox webdriver could not be verified for use in Firefox and has been disabled".  I have already toggled xpinstall.signatures.required to false to deal with the problem with unsigned extensions so this may not be the issue.  Any suggestions for making webdriver work with Firefox?</p>
