This is the Addon I've been looking for.
For Literally Years. Ever since this was removed from the main FF. I'm extremely glad to see it's back again!
Wonderful job you've done with it. I only regret that I cannot give it 6 stars.

After browser restart all tabs are gone, including panorama sets. Recovering profiles doesn't help. Where are the settings being stored?

I lost all my tabs. Immediately after launch, this add-on removes all your tabs and transfers it its own menu. But it cannot work with a large number of tabs. After installation, my browser freezes. I restarted it, but it worked unbearably slow and freezing every seconds. I removed the add-on and all my tabs is gone. Why is there no warning about the number of opened tabs?

Потерял все свои вкладки. Сразу после запуска оно трет все ваши вкладки и переносит их к себе. Но дополнение не может обработать большое количество вкладок. После запуска браузер завис. После перезапуска был в нерабочем состоянии, тормозил, фризился каждую секунду. Снес дополнение, и вместе с ним ушли и все мои вкладки. Никакого предупреждения о количестве открытых вкладок нет.

This is exactly what I've been looking for, can manage tabs in visual groups and resize them as needed.

Can also drag and drop a tab from one group into the white space and it automatically creates a new tab group.

Thank you for developing this!

First day of use and i lost my tabs

Really, REALLY great addon. One of the 3 most important. The only issue it has is that it doesn't play well with Tree Style Tabs (https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/?src=search) and will often jump into another tab group when closing a tab.

Does not work, returned to the original

My Tab Groups Randomly Resets All The Time

I keep losing my groups and having to re-sort everything.

Thank you for bringing back the old good feature. I love it. Good for organizing too many tab.

The panorama tab group icon appears on the bookmark toolbar but clicking it does nothing.

Thank you for making this great add-on! It's easy to use and has improved my efficiency. It's nice to be able to visualize all my tabs at once and organize them into groups.

Must have addon! Latest update got a huge performance-boost, now it opens instantly - truly surpassed the original functionality from firefox by a good bit! :)

А на него что,- после перезагрузки браузера склероз нападает?! Почему он не запоминает открытые и настроенные в нем же самом группы вкладок?! Какой в нем тогда вообще смысл?!

Обновление 0.8.9 стало работать очень быстро! Спасибо!
