I cannot work out what is going wrong here but using Firefox 48.0.2 [latest] on my home Mac which has El Capitan 10.11.6 as its OS the following occurs when attempting to view the forums. At work where I also use Firefox 48.0.2 but an early version of the OS there is no issues. Also here at home, Chrome is working fine. I have cleared the cache etc but no change. Any suggestions?
