Firefox fails to download bundles "too much recursion"

Unity Engine
1

We are having a 100% crash trying to download a bundle in firefox. Its on the “yield return www;” and the error that shows in firefox console is “Script error: too much recursion”. The same code runs fine in Chrome.

This is a Facebook game. We are using a custom node.js server, and files hosted on AWS S3/Cloudfront, all using HTTPS. We’ve used 5.1 up to the current beta, and the problem exists in all versions.

Is anyone able to download bundles successfully on Firefox? I’d like to determine if its our setup, or a global firefox error.

We’ve posted a bug about this along with an example project to unity, but its not public. We may be able to post a link to the public build later today.

Thanks

This will work in Chrome, but fail in Firefox.

We have confirmed that the assumption on this thread, that iframes are at fault, is probably the issue:

We created a direct link to test and the same exact code / html loads in firefox correctly. So, it seems Firefox has architectural issues with Facebook and Kongregate (both require iframes) that have no easy answers. I hope Unity can figure out a work around, otherwise WebGl on these platforms could be quite a ways off.
