You can modify easily the current version to use with TB 3.1 (works fine) until an official version is released.
Just edit the install.rdf file inside the .xpi file (it´s a zipped archive) with a text editor and change the line 20: 3.0.*
with:
3.*
Save and reinstall the nostalgy-0.2.23-tb+sm.xpi extension
