Rated 5 out of 5 stars

I use, rely upon and enjoy this add-on. The cute little fox poking out at start up is entertaining! The To Do List, Reminders and Calendar are very helpful, interactive and easy to use. BUT Not available for Firefox 4.0b8. PLEASE UPGRADE.

This review is for a previous version of the add-on (1.9.9.1.1-signed). 

Thanks for the kind review. It should now be updated to the latest beta version of FF4.
Thanks.
