Did the slow script dialog show up for you? I got one. The first time I used it to stop the script, and things seemed to be OK after that. I tried it again and let the script continue, and that eventually worked too.
The page hung for me, but not for so long. It didn't even made the slow script dialog show up. Checking about:telemetry I see Hang Report #1 (8 seconds) js::GCMarker::processMarkStackTop(js::SliceBudget &) (in mozjs.pdb) js::GCMarker::drainMarkStack(js::SliceBudget &) (in mozjs.pdb) GCCycle (in mozjs.pdb) Collect (in mozjs.pdb) js::GCSlice(JSRuntime *,js::JSGCInvocationKind,JS::gcreason::Reason,__int64) (in mozjs.pdb) js_InvokeOperationCallback(JSContext *) (in mozjs.pdb) js::jit::InterruptCheck(JSContext *) (in mozjs.pdb) js::jit::CheckOverRecursed(JSContext *) (in mozjs.pdb) -0x1 -0x1 -0x1
