When playing FarmVille I continually get a window poping open that is title "about blank" it then closes and pops open again, preventing me from doing anything on Farmville how can I stop this?

Question

when trying to play FarmVille with Firefox on my laptop, a window continually pops open with the title "about blank" then it closes, and pops open again right away. Because of this I can not manage to do anything on the FarmVille screen. This does NOT happen on my desktop machine. Both are running Windows 7 64 bit. How can I prevent the window from poping up all the time? Something is continually sending a request, but I do not know what it is. Thank you for any help or suggestions. By the way, Google Chrome works perfectly, but I prefer Firefox.

Answer 1

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.
