I migrated an addon (not one I wrote) to TB 64+. It works, but the XUL preferences window is missing its groupbox labels.

The code is here:  
[https://github.com/revad/use\_bcc\_instead\_C](https://github.com/revad/use_bcc_instead_C)  
and the issue here:  
[https://github.com/revad/use\_bcc\_instead\_C/issues/1](https://github.com/revad/use_bcc_instead_C/issues/1)

Can anybody here shed any light on this?  
TIA  
Dave (aka revad)

I asked in bugzilla and got confirmation that, as I suspected, this is caused by the removal of groupbox bindings under bug 1493844: [https://bugzilla.mozilla.org/show\_bug.cgi?id=1476259#c17](https://bugzilla.mozilla.org/show_bug.cgi?id=1476259#c17)
