Assegnate 5 su 5 stelle

This was an easy to install Add-On. Just clicked 'Add to firefox' and it was ready to use. I did not get this as part of any malware, this isn't toolbar, my tabs work, no functionality has changed. All this did is add Ask.com to the list of search engines available in the top right corner of Firefox(Why it wasn't added to begin with puzzles me).
I highly recommend this Add-On and search engine.
