Rated 3 out of 5 stars

This addon is useful for finding leaks, but it can be very difficult to differentiate real leaks from "fake" ones.

For example any time I close a tab in Firefox 3.0 RC3 I get about 15 popups telling me that "[Window]" has leaked followed shortly after telling me that all leaks have been "reclaimed". Net result is 30 pop-up windows for 0 leaks.

It would be much better if the add-on could differentiate permanent leaks, from temporary ones.

That said if you are trying to test your extension and have nothing else installed in Firefox, this extension is useful.

This review is for a previous version of the add-on (0.4.2).
