Can not use new editor with Firefox

Hi,

Finally decided to have a go at the new editor... didnt get very far, because when opening the editor to look at an already translated job, I only see empty segments (source and target) and no text.

When opening a new job for translation, I donot see the source and I cannot add anything in the target.

See below

I am using Firefox 61.01 (32 bit)

Please donot advise me to use Chrome because I will not use that product.

Please advise
