I'm trying to run a asm.js code in Firefox 29 but I get this warning from debugger console:

TypeError: asm.js type error: Disabled by debugger

Here is the code:

function boo() {
    "use asm";

    var result = 0;
    for (var i = 0; i < 1000000000; i = (i + 1) | 0) {
        var result = result + i | 0;
    }
}

It seems the asm.js is disable when I work with it, How can I fix this issue?

• javascript
• firefox
• asm.js

You can't. Asm.js optimizations aren't possible when the debugger is running. It will fallback to be executed as normal JS and can debugged that way. In which sense do you want to work with asm.js code?
