Rated 5 out of 5 stars
It is an execellent idea to make available in the memory ten pieces of text, and not just the last copied text item.
Super Paste! works as promised, just follow the excellent description.
I would add a tip to the description.
When you have chosen a stored item of text to paste, you can also paste this item outside Firefox. But be sure to make the selection inside Firefox.
I am very pleased with this add-on.
