Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
the extension create a file named "storeTab.sto" which save the urls of tabs on your firefox profile roots.
someone may choose the "Show my windows and tabs from last time" options to remember the links.If you choose this option,everytime you open firefox,it'll recover the links you closed last time without asking.I think most users don't want that.If you use storeTab,you can recover the links when you want to recover!
