404 Errors with Firefox 55.0 on CDN Static Resources

I am a website administrator and I have noticed a lot of 404 errors in my site's CDN access logs. The requested paths are all "/", and the user-agents are all "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:41.0) Gecko/20100101 Firefox/55.0". The client source IPs are distributed, and the ASNs are also diverse. The requests are made to a domain specifically used for static resources (css, js), and the referer is my main website. I suspect there might be a specific bug with Firefox/55.0. Can anyone help me confirm this?
