I can't live without this add-on. This is an essential Firefox add-on for me. Great job!

Only drawback: It makes it very easy to have too many tabs open. :-)

Still the best vertical tabs addon, especially paired with the TST bookmark sub-extension, which allows to have your tabs and bookmarks visible in the sidebar at the same time. Just awesome!

it seems really cool the diagrams and the examples and the explanation that I got to see this! Amazing job making your own add-ons for Firefox fire

Pretty good! Now I can switch tabs easily! :D

Прекрасное дополнение!!! Без него мне не комфортно работать в браузере Firefox. Благодарен автору!

Very nice!

Great. It doesn't get any better.

Seeing this extension on a friend's pc is the reason I switched from chrome, by far the most useful extension I have ever used.

Wow
