DLP rule note firing for Firefox or Edge brwoser

In fact, its not firing for email client i.e. Outlook as well. 

Edge is not really what I would consider a ready for production product, there are many applications it simply does not work with, it does not have clear specific admx templates to configure for edge alone either.  I actually block it with Sophos Central.  I cannot speak for Firefox with DLP either, however I can help with Outlook.  I would look to my posts here where it is discussed in more depth.
