Excellent.. 1 more feature please Rated 5 out of 5 stars
If you have 100 extensions, then you will have 101 after trying this one.
The features of this extension should be added to FF3 by default. It is a real time saver.
Please Fix: Comparability with FF3 (I had to force the installation). Also, provide a better location for the Sort box so no right or left scrolling is needed when opening the Addons manager in the sidebar.
Please Add: sorting extensions by installation date or at least by installation order (starting from the most recent) since this is very important when disabling newly added extensions one by one to isolate a bug or conflict.
