"No Site Configured at This Address"?
Every so often I start up Firefox and instead of loading Yahoo (my start page) it says 'No site configured at this address'. Yahoo is still there, like if i enter news.yahoo.com or answers.yahoo.com, etc. But Yahoo itself is not available. This goes on for a few days and then Yahoo is back.
This started yesterday. Today I find Craigslist is also 'No site configured at this address'.
What causes this? How can I fix it?
