HTML 5 Script Error

[anonymous_user_a08c0bf2]

I create simple FPS test scene without additional geometry but I still have the same error. I’m using UE4 4.8.3 and emscripten 1.29

But when I install emscripten 1.29, some error appears and program install version 1.34.
In prompt window I do the next steps:

1. emsdk install sdk-1.29.0-64bit
2. emsdk activate sdk-1.29.0-64bit
   and it’s ok.

In Unreal Engine I choose emscripten 1.29 and package is successfully complete.
In FF appears error as above.

Have you updated your browser? I’ve been able to run HTML5 projects on without any trouble lately, could you tell me the process that you’re taking to push the project to HTML5? This may be an issue where an AnswerHub post may be necessary.

Thanks!
