This is perfect and amazing and full of useful features, like moving all the tabs into one firefox tab or window, even pinning it, and grouping the tabs in that window, naming them, locking them so that when you open the link you won't lose the tab in OneTab, EVEN being able to share all your tab links or a subgroup of your tabs to your frined via a generated link! just by installing OneTab and managing your tabs you can have a new firefox! It feels great to use it, DONT MISS IT.
