1.) are you administrator?
2.) are you using unix?
3.)try to use lower version of firefox
Thank you for replying. I am not admin. Just trying to run on my windows 7 machine.
My Firefox version is: 41.0.2
Chrome version: 46.0.2490.80 m
Operating system. Windows 7 64 bit.
I googled it a lot most people suggested same that low the browser version but question is which one then? Anyway I was hoping there was any other way to resolve this. But in any case thanks for replying.
i'm afraid that you have to lower the version of firefox. no other way around it.
