websudoku.com doesn't load in firefox, but does load in IE 9.0 - why?

The tab shows text - Web Sudoku - Billions of Free Sudoku Puzzles to Play Online, but the site doesn't appear. I have Add-ons Adblock plus, Flagfox 4.2, Java console 6.0.33.

Brilliant - I didn't know about starting firefox in safe mode.

The problem was Adblock Plus, which I have now disabled - bit annoying, as it stops ads, but I can re-enable it if not playing sudoku!

Many thanks, I owe you......
