This add-on, storeTab, is an interesting add-on for Firefox that allows you to open many tabs and then in a simple click, save those tabs for later. You can reopen your browser and restore the tabs you saved at any time too.
Here is a little more about the add-on from the developer:
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!
