Is a page broken or misbehaving? Are you experiencing issues with content and resources within a Firefly page?
Examples of strange behaviour could be no Edit button showing, no top bar showing, or redirecting to another page with no chance to edit the page.
Firefly will automatically display Office documents in a Microsoft web viewer. As Firefly needs to connect to Microsoft for this feature to work, make sure that any firewall or proxy is not blocking requests to external servers.
If you're running legacy versions of Microsoft Office, particularly Office 2007 or Office 2010 pre-SP2, you may experience problems using the Office live editing features in Firefly after update 5.1.9.
