Edit the .rdf file in the xpi. Change the 3.1* to 5.0*. Add it back to the xpi and it will load into TB 5.0. Works find as well as I can see.

Open the xpi file with 7zip, winrar or whatever you use. Edit the .rdf file and replace the 3.1* with 5.0*. Save it back to the xpi and install it. Works fine as far as I can tell.
