When opening document from Firefox link or Thunderbird attachment LibreOffice presents dialog:
"Document file 'foo.xlsx' is read-only.
Open read-only or select Notify to open read-only and get notified when the document becomes editable."
With buttons to open read-only, notify or cancel.
These files are temporary and as such will not become editable. The dialog is waste of user's time, the notification on top of the document window is quite sufficient.
Steps to Reproduce:
1. Click Office attachment from Thunderbird or click link to an Office file in Firefox.
2. Open the file in LibreOffice.
LibreOffice presents an document is read-only dialog.
No read-only dialog should be presented.
User Profile Reset: No
