 The crash is reproducible

 I think there may be two different crash scenarios we're seeing. The

 F libc    : Fatal signal 11 (SIGSEGV), code 1, fault addr 0xfffffff0 in
 tid 15134 (JS Helper)

 F MOZ_Assert: Assertion failure: [infer failure] Missing type in object
 [Object * 0x92f15310] _dirty: float, at
 F MOZ_CRASH: Hit MOZ_CRASH() at /opt/Orfox/external/tor-

 Appears in the javascript runtime. This has been the main focus.

 However, I am not seeing that crash anymore (and now I have doubt the
 above webpage actually reproduced that crash. Below is the current crash I
 see - stack corruption.

 adb| [23490] WARNING: Write failed (non-fatal): file

 And from adb:
 F/libc    (13049): Fatal signal 11 (SIGSEGV), code 2, fault addr
 0x74736e75 in tid 13071 (Gecko)

 igt0, can you still reproduce the first crash?
