Over full service,

I'm using it EXTENSIVELY!
But, i have to say something
It will be even better if it has a tree structure. The Treeview control from old Windows Explorer, which is in Visual Basis and MSCOMCTL1 is amazing, and I love it; I'm programmer myself and i love it. If was implemented here, was even better.

Not the same like Tab Mix Plus but OneTab is also enough good.

awesome!
But, when having plenty of tabs, it's hard to find 'onetab' between them to browse some links inside. so it will be more handy to pop up a panel to operate instead of a tab.
More, most of the favicons are broken.

Si eres de los que usan muchas pestañas a la vez en cada sesión de Mozilla, OneTab es una excelente opción. Convierte todas las pestañas en una única lista bien organizada dentro de una sola pestaña, que quedará a tu disposición incluso si cierras la sesión. Cuando vuelvas a iniciar la sesión, pulsas el icono de OneTab, y aparecerá una pestaña con todos los grupos de pestañas que hayas guardado, bajo el nombre que les hayas asignado. Y en cualquier momento puedes restaurar todas las pestañas (o las que elijas) con un solo clic. Por supuesto, esto aligera extraordinariamente el uso de la RAM. De veras que funciona. Muchas gracias.

The most important extension for web-research-professionals

Amazing utility.
No need to keep all tabs open, you can always refer to One tab

Very useful.

Saves a lot of time when deciding to bookmark things or just close the browser; with OneTab I can always get back to the stack of tabs I was using.

At the risk of sounding dramatic, One Tab has changed my life. As a researcher I often opened too many tabs and my laptop would stop responding, resulting in having t re-start it, losing the saved tabs. One Tab not only lets me save tabs, but save them in organized groups if desired.

love it!

Works Great! OneTab is a life saver, especially after the update to the new firefox has left me without a good quality session manager. :)

Handy +

Great to keep your FF sessions clutter-free. Only thing missing is synching across devices...

Muy buena pero hace fala guardar la información en una cuenta online.

Is just What I need because I am the type of guy that uses from 15 to 30 or even more tabs!

Why?

Well, because I am very curious and i get easily lost in wikipedia articles or youtube videos, I usually start my journey doing research about "x" and many hours later I find out I got numerous tabs open and I am reading "ñ"!!!

So, thanks to OneTab, with one click I can make my internet navigation easier by just compressing all of that into one tab that has yhe links of all the webpages I was into.

This is awesome!

This is very useful extension. I do not have a browser full of tabs since I installed it. Now I have control over the sites I have visited and want to visit again. Now, instead bookmarking, I can store tabs in OneTab when I do not want to lose the bookmark of a site among all the other bookmarks.

Just lost all my tabs after a crash. The OneTab list is totally empty. What a waste. Won't be using this again.
