All JavaScript code with workers have this problem on localhost. Problem is that almost none developer use workers.

I write on Github educational code for workers https://github.com/bedna-KU/PHPXHR and this throw the same error. Before code works OK (older versions FF). On others browsers work OK.

Workers is technology of the future, each processes have own thread and no freeze browser.

Please, how can I help?

Thanks for this PHPXHR!
I tested it locally and it works fine: I run it using apache+php5 locally, loading it from http://localhost/PHPXHR 

Can you tell me if your setup is similar to mine? Thanks!
