I am receiving errors when trying to use Selenium with ARD and Firefox 58.
CA Agile Requirements Designer (ARD)- Agile Designer 
Unfortunately, as of now, Selenium Builder only works with Firefox version 56 or below. The latest version of Firefox is 58.
To resolve this, please do the following:
- Install Firefox 56 (or downgrade if you already have a later version).
- Switch off automatic updates in Firefox, otherwise it will always download and install the latest version.
