Hi tlk2012, I think yours is the third problem posted today with Yahoo as the home page. I'll link to the other threads for reference and commiseration, but there isn't a solution in them yet:

• https://support.mozilla.org/questions/1289550

Maybe the three of you can recognize some common factor that might be causing this?

You can check the Web Console and Network Monitor for possible reported errors.

• "3-bar" menu button or Tools -> Web Developer

You can check the Network Monitor to see if content is blocked or otherwise fails to load.
