Very good, a lot of tabs can be located faster, the same tabs open pages are also organized together!

This extension makes Firefox dreadfully slow. I just removed it and it feels like breathing again.

The tool looked promising, but it really makes web surfing extremely difficult, sometimes impossible: some blogs became simply impossible to show. Also, a lot of swapping occured when using that tool, so I guess it uses way too much memory.

I am back for good to the simple vertical panel Firefox provides.

Great for managing tabs and tasks and research and group them and…

I can't live without it! I only miss it had tab search and a tab counter.

This is probably a great extension for some people, but I couldn't get behind it since I couldn't get rid of my top bar.

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. :-)

タブが表示されなくなることが多々ありますそれさえ直れば完璧です。

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!

Cannot uninstall this extension.

I removed it through Firefox and it does not show up in extensions, but it is still there in context menus and in functionality.

I don't know how to remove it now. It's occupying the top of my context menus when I right click, but there is nothing to uninstall.
