This is probably just due to a race condition, and potentially how the browsers handle threading and caching. You are calling loadFile() multiple times, which will append to an open queue, or start a new one. Because you are loading the same file, one of the browsers is returning immediately causing an additional load, the other one has a short delay, resulting in the file getting added to the internal queue.

If you are loading separate files, it should not happen.

The best practice is to append to a queue array, and use loadManifest() instead one time.

Hope that helps!

I was loading different files on my local project and still queue callback fired for each file on Firefox, but loading via loadManifest() fixed the problem. Thank you for your answer, closing.
