I'm starting using Linux (Ubuntu 12.04). I've had many problems to access all Yahoo's pages. Only Yahoo, others sites I access well.
I don't know why it happens! It only happens with Yahoo's pages.
Please see the images. I'm using Firefox browser. How I am new in this forum, I can't post images, then I put the URL's with them.

The images of Yahoo pages are in Portuguese because I'm in Brazil.
I think this information is important: In my computer I have two operational systems (Windows 7 and Ubuntu 12.04). In the Windows 7 using Firefox the Yahoo pages works normally.
