What is it? Rated 5 out of 5 stars
I don't get it. Why would you want to do spreadsheet work in Firefox instead of a powerful data app? I am missing something. What is the point of this extension?
Are you saying it grabs information tables from Websites that are not visible to the general browser? If so, explain. Are we talking about simple site-visit data and site indexes from a website, or are we talking about entire reference tables, like product lists from a retailer? If so, are we talking .Net apps too? That would be crazy... and awesome.
