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
