I have an Infopath form template used for a SharePoint form library. I have the library set to only open the forms in the client. When i create a new document, it only opens in the client, but when I double click an existing item for editing, first it opens it in the browser and then launches the client. Weird.
I am using latest version of FF
Office 365 E3 plan with Infopath 2013 installed locally as part of E3 package
