Спасибо за отличное дополнение которым пользуюсь уже много лет

This extension is the only reason I am still using Firefox in 2025.
No other browser has automatic tab nesting.

Can this extension be used to capture information about a FF tab that somehow opens then closes within a second? If so, what settings of this extension will enable this?...I haven't been able to find the correct setting to capture this info.

This extension revolutionized my browser experience. I can work and search much, much better now.
Gonna test this with vertical tabs on the browser soon to see how it goes

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.
