 Thanks. This is using exactly the same branch as we have in 6.0.1. Thus,
 you can work around that crash for now by either installing a fresh new
 Tor Browser, or, if you are adventurous, just deleting the asmjs related
 files in your profile directory (see comment:16 and assuming Facebook is
 caching such stuff too) should help, too.
