I used to have this Addon on the Chrome Browser. Now I tested it yesterday on Firefox. The only feature that this addon is lacking, is the <> to find Tabs Quickly. And the ability to separate Tabs into several Groups. For Example: YouTube Group (with all the video tabs), Design Group (tabs for design websites), etc...
Because I have more than 1000 tabs open So I can not find easily what I want. I will update my review when They add these two important features.

It's session manager and tab suspender all in one. It can also share saved web urls.

I am new with this ad and want like to know more about it

Please add a dark theme option

This is the closest thing I've seen to the "set tabs aside" feature from edge. Very helpful at putting all my tabs in one place to be seen easily. I highly recommend giving this a try.

Wow! I couldn't imagine more!

Lifesaver.

Firefox auf Android 6.1 (ein Gerät mit 4 Rechenkernen, 1GB Arbeitsspeicher, ... Damit wäre die Apollo-Mission ein Kinderspiel gewesen, insbesondere Apollo 13). Das Addon macht aus 300 Tabs, mit denen der Browser noch problemlos arbeiten kann 2 (ZWEI!) Einträge in der erzeugten Liste und vernichtet die Web-Links zuverlässig. Wie schwer kann es sein aus Tablinks eine Liste mit 300 Zeilen zu erzeugen? Unter Windows funktioniert es!?
0 Points, 0 Punkte. Angesichts des Schadenspotentials kann man nicht von kostenlosem Addon sorechen. Caution! Dangerous!

The Android version is not well adapted

One-tab doesn't work in newest Firefox Dev for Linux,
it's only showed white screen.
Please fix it. I use it every day.
