[Addons.mozilla.org](http://Addons.mozilla.org) Additions for Firefox (ru) If you open any extension and create a new collection from its page, then this extension immediately falls into this collection.

But on its page this is not reflected. And can not replace the collection. The site does not recognize its collection. Writes, “extension in another collection”.

The desired standard sequence : first a collection, then add extensions to it.
