One of the most useful, lightweight Firefox add-ons, it displays a clear, flip-through, and scrollable (!) list of all tabs in the current window and offers the ability to:
• view URL/title, toggle
• bookmark,
• pin tab,
• reload tab,
• close tab, and
• discard tab.

It can be used via keyboard shortcut, click buttons, or the context menu.

This allows you to close tabs you no longer need, even in a chaotic mess of up to thousands of tabs. It uses very few resources (RAM and processing power), even with a large number of tabs open. Furthermore, it allows you to keep track of the number of tabs in a window at all times by constantly displaying the number of open tabs. It works perfectly and flawlessly for me, better than similar tab tools.

Nice extension :) Is it possible to add an option to only display pinned tabs ? Thanks !

Good but,

1.I would like the panel is stay opened when the tab is removed.
Without this feature, closing multiple tabs is inconvenient.
If this feature is supported, I would like to continue using it.

2.Button looks bad.
Especially I like black 'X' remove button which is used a lot these days rather than red '-' button.

3.Speaking of terms, "Close" is better than "Remove"

Edit: Thank you for adopting these features I requested in the new version.

Nice, fast and stable. Especially like the gray-out (meaning "not loaded yet") indicator.
Several enhancement I want:
- Text search.
- In the tooltip popup, option to show both the header and the URL at the same time.

It's working after 2-3 times open close the list. At first it will be blank

A very nice add-on. I especialy like the keyboard navigation and tab count in the icon.

This is everything I've ever wanted from a tab listing extension! Well, almost everything. I always have several YT tabs open, could you add the symbol for which tabs are playing audio, please? :)

Interesting extension! But I want also neutral gray icon on Firefox toolbar. Please add gray icon to options. Is it possible? Thanks!

Update: Very fast response. Wow! Thanks. I now rate 5/5.

This addon is perfect and indispensable.
One question: is it possible to replace the icon color orange with a freely selectable color?

update:
I was able to change the icon color with a css-code.
Still it's a very good addon, thanks for that.

100% Perfect.
For me, this add on is as essential as, tab mix plus, noscript, among others.
The keyboard shortcuts, is what I was looking for, for this kind of add on.
Don't forget to read the detailed instructions in the "About this extension" section.
