Website produces errors only in Firefox

Healthline.com will not load. Gives lines of errors on their homepage.

I posted this topic last week with a list of some errors but my post was rejected by admin.

Can anyone comment on this?

This is a bump of original post. Six years since this bug at the Healthline was reported and still not fixed!

Well, finally, it seems in the last few weeks the issue with the Healthline site no longer exists. Either at their end or at Mozilla’s. But whoever it was, thanks.
