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.

Great, but it needs a search bar, to look for the tab you can't find (because there are too many, or because it is in a collapsed group).

5/5 until recent update, I don't know how to remove the new "Tree Style Tab" header in the sidebar above all my tabs but below bookmarks. 2/5 until this is fixed

I was having issues opening new links on new tabs, they always went to the far right. After uninstalling the plugin they started to behave normally opening next to my current tab.

Very useful tool white managing abundant tabs!

Very good idea unfortunately looks ugly

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

Cool

Extremely useful for organisation

However, it does often glitch in one particular way. I keep it on the right side of my desktop, but sometimes the formatting gets messed up where the crosses all appear on the left and the down arrows on the right, with no indentations below each tree, undermining its utility

閉じたタブを開き直す で最後に閉じたタブだけじゃなくて直近10件くらいから選択できたら嬉しい
