I'm getting a similar thing. Foxtrot.com pops up a blanks window, in a new tab, with just "{"status":"SUCCESS"}" in it and an address of "http://wd.sharethis.com/api/setCache_ws.php". The created tab also grabs the focus. The issue is somehow related to the preference, "Links to other sites: open in a new tab" as it doesn't happen if I set a different action. Background windows are not popping up, as far as I've seen.
