been using this for a couple years now and it's incredibly nice to see all my (many, many) tabs organized into little branches. great to use with Auto Tab Discard

Muy buena ayuda

Using this for couple years now and enjoying it much all the time. Extremely useful add-on, first one I install for myself on new computer. Kudos to Author :)

Thank you Piro for creating and maintaining this FF extension. It is one of my most importand FF extensions!

I have tried many Vertical Tab extensions. TST is by far the most useful, stable and trustworthy. It has earned its Firefox recommendation by its superiority in all aspects. I also have tried the internal vertical tab view of Firefox. But it is almost not configurable.

Very useful tool white managing abundant tabs!

Отличный VPN, быстро подключается, обеспечивает безопасность и анонимность в сети. Рекомендую!

Cool
