Sites not working correctly with Firefox Quantum

Sites not working correctly with Firefox Quantum

HI,

I use Firefox Quantum version 57.0.4. When embedding a Zoho calendar on to my webpage, FF Quantum doesn't render the page in the editor, which is not an issue, but I am also unable to publish the website. Instead, the "please wait" logo keeps going until I reload the editor page..

The embedded calendar doesn't render when I access my website via the public URL using FF Quantum. No amount of reloading appears to fix this.

I have no issues with Chrome version 63

Has FF Quantum been tested or is there something else wrong that is specific to my site?

Thanks

Alan
