Unity WebGL in Firefox / Invalid State Error

Unity Engine
1

Hi,

we have a little problem with our finished WebGL Project in Firefox. Chrome and Safari work like a charm, but in Firefox we are getting following error:

An error occured running the Unity content on this page. See your browser’s JavaScript console for more info. The error was:InvalidStateError

This error can be accepted by hitting ok and going on and playing the WebGL file. Nevertheless it behaves different to the executions in Chrome and Safari. We have a synchronised sound and motion and start this at the same time by script. In Chrome and Safari it is perfectly on point. In Firefox it is totally off. The java Script console points to this - > "Unable to find type [UnityEngine.dll]UnityEngine.SharedBetweenAnimatorsAttribute
This seems to be the reason*,* but I don not know how to fix this!

Here is what console says alltogether:

Is your Firefox up-to-date? I remember older versions showing this error.

Hey Jonas,

I just checked it. I work on two machines in parallel both win7-64. On the one i have Firefox 33.1.1 that ist the version giving the state error. On the other machine I have version 33.1. Slightly older but giving no error. Besides from that in both Firefox versions compared to chrome I have a totally asychrone audio and motion.
Is there a way to send you the link to the webgl file or project. May be interesting for you to check this!? I do not want to post this here as it is not meant to be shown public.

Yes, just use our bug report tool!

Hello, I also have this error
Unable to find type [UnityEngine.dll]UnityEngine.SharedBetweenAnimatorsAttribute

showing up on both
Firefox 33.1.1
&
Google Chrome 38

I believe that is a bug introduced in b13 or so. The error message can be ignored for now.

I sent you the file via bug report. Left click on one of the figures to start the animation to beat. Best to be seen in Chrome or Unity Editor how it should be.
But I just discovered something new! I changed optimization level from fast to fastest and now the error is gone. This just leaves me with the problem that audio and and motion are not synchrone on Firefox. Maybe you have a hint there for me to fix this.

Hi Jonas,
have you had the time to take a look into the file I sent you via bug report? I am still trying to get Firefox working with our project. To me it seems that Firefox is somehow slower in interpreting the WebGL code!? Could this be??
