Удивительно, что у данного расширения пока так мало пользователей - ведь это по сути единственное пока расширение для нового файерфокса, заменяющее прежнее расширение Showcase, позволявшее выводить список открытых вкладок с миниатюрами - очень удобно для визуального поиска нужных вкладок, когда их открыто множество. Это вообще расширение, которое должно быть у всех, и, надеюсь, что оно скоро наберёт намного больше пользователей.

The Control+Shift+F shortcut is not working on OSX. Cmd+Shift+F is default system shortcut for full-screen.
Please allow customization of shortcut. I understand you want to minimize configuration, but this is very individual setting.
It would be *awesome* if we could drag-n-drop tabs from one container to another (that would reopen the same URL, possibly with history, in the target container while closing the tab in the source container) or between the windows..

Lots of potential in this extension.

Drag and drop to re-arrange tabs doesn't work. I can drag a tab, but dropping makes nothing

Neat extension, but hotkey isn't working for me on Windows. Makes it much less useful.

As reported by previous user, keyboard shortcut doesn't work on Mac. Please please fix that or allow customizable shortcut.

Comes closest to the old Tab Manager extension that Mozilla put on earlier versions of Firefox. Would love the ability to customize the keyboard shortcut, as I'm on a Mac and Command+Shift+F makes the current app fullscreen. Ctrl+Shift+F does nothing. Otherwise great!

Please consider add support of "Hide Tab" API, which many new "Tab Group" extension rely on.

Good. Although consider making it more intuitive for new users (especially the dragging and dropping of tabs to re-arrange them).
