Hello David,
I sent you an email, but thought I'd try this path as well. I've been using Selenium Builder for a year now, and I have built-up a huge library of scripts. As of now, it seems like I can't use Selenium Builder with the latest FF Quantum. I'm not even able to install the Addon. it tells me, my version of FF is incompatible with se-builder. Can you please let us know if Selenium Builder will be upgraded to work with the latest FF version(s)?
Thank you,
Lin-
