It might help to upgrade gvfs to version 1.57.2-2 from unstable (you 
didn't include the versions of related packages in your bug report, so I 
can't tell whether you already have that). gvfs 1.57.2-2 fixes #1101025 
which could have an impact here.

Or, Firefox or some component used by Firefox might be creating a 
GFileInfo without asking for it to contain the standard::content-type 
field, and then assuming that it will contain that information anyway. 
If that's the case then it's a programming error in Firefox (or in some 
component used by it).

Is this the firefox package from unstable, or is it a third-party 
package from outside Debian?

This is a separate issue, and it is a Firefox or library bug: it's 
asking for a GtkFileChooser and assuming that the result will be a 
GtkWindow, but that is not an API guarantee (and in particular it is not 
true when using the portal-based file chooser dialogs).
