Im only getting results in the 'plausible typos' column, also on one of the results I checked after 13 results I had a popup error "Sorry but the extension you suplied is not supported". Clicking ok just popped the error straight back up until I closed firefox with task manager.

edit: took around 4 minutes for results to start appearing in other columns.

Appears the longer the domain is the more plausable typos there are and the longer it takes to populate the other columns: searching for talkfreelance.com took 6 minutes to finish the first column and over 12 mins in total to populate all the others. Maybe limit the first column to a specified amount of results?

Finally is there a list of tld/cctld's you can search for?
