I have been using this add on for ages. It has been immensely useful, among the most useful of all extensions I'd say without exaggeration. However,I have learned this this invaluable add on is now deprecated and in fact, will no longer be usable with future builds of FF beyond November. This is a mistake. This functionality should be built in to FF not removed completely.

I urge the developers to incorporate this add on as an out-of-the-box feature in future releases of FF rather than kill it off completely.
