Since I am testing Salesforce, I can´t see my Developer Console.

The first message is "Loading configuration...". 
Then I read "Loading workspace...", and that´s all.
I can´t see nothing else.

My Internet connection is perfect, and I´m using Firefox and Google Chrome.

I don´t understand what´s happening.

Please, help me!

Thank you.
