Review for Update Notifier by Webgoji
Rated 4 out of 5 stars
I have to agree with em28. This should really be a default function with Firefox. It's invaluable if you use more than one extension or theme. I've used this for quite a while now and have never had any problems.
This review is for a previous version of the add-on (0.1.5.3).To create your own collections, you must have a Mozilla Add-ons account.
