It's a good extension. I used it all the time with Google Chrome, and it's awesome to have quotes, pictures, and the to-do list is especially useful. It's a refreshing alternative to the default new tab page.

However, with firefox, there are significant bugs that need to be fixed before it is a great extension. With the to-do list, for instance, the arrows do not move the typing cursor. And if you try to move a to-do box into a different slot on the list, it redirects to a strange website (edmunds.com, a new/used car website...???)

I hope these bugs will be fixed soon so this app can be as good as it was with chrome
