firefox 56 doesn't load trello after logon

I've updated my fedora 25 and it seem to load new firefox browser. After this I can't continue w/ trello after login - no elements to operate. I've disabled plugins, removed cookies and cache, restarted firefox. This doesn't help. With F12 console  I see error about corrupt file (which I can download w/ wget w/o error):

If that doesn’t load, there are a few common potential causes, such as DNS cache issues or a firewall blocking access. For more information about how to troubleshoot those issues, please see: 


If none of that is working, I would suggest reaching out to us directly via, and we'll be glad to look into it!
