Mozilla killed it by wrecking the Add-on Collector! Rated 1 out of 5 stars
I thank the developer for making what once was a great add-on. Now after reading the earlier review I do wonder if it was behind some of the recent screwy behavior though. What has happened is they killed the add-on collector which enabled this one to work. The Add-on Collector had been getting steadily worse- and in recent months had totally shut down before they put it out of it's misery .This- combined with an endless list of mistakes, bugs and other problems ever since Mozilla started their suicidal "rapid release" policy- completely killed collections as we know them. It was a good ride while it lasted...This user has 2 previous reviews of this add-on.
