Good extension, does everything that an AddOn like this should do.

To all those who write that all of your data is lost in onetime.
Have you tried making a backup locally on the hard drive, after 100 pages saved in OneTab? Or do you all think that you can save an infinite number of pages without the memory running out?😒

very simple and easy to use

All of my saved pages randomly disappeared.

Fantastic tool and has been often reliable. I would pay them for this if I could.

UPDATE 2: I found it - when you run out of disk space, OneTab freezes, becomes completely unresponsive, doesn't save new links and doesn't open already saved ones. And most importantly: AFTER FIREFOX RESTART, IT DELETES ALL SAVED LINKS !!!

UPDATE: Today it deleted all OneTab data again when I had not enough free disk space. (I learned my lesson first time, I always back it up). It's not robust. Beware of that.

It works well. But I already have lost all my data (about a thousand links) in OneTab once.

Onetab is NOT a backup tool !!

Fortunately, it has a great import/export function that is very easy to create backups. So use it! Don't make same mistake as I did.

Decided to check on this extension, and no warning, no asking, it just in a moment screw all my tabs groups.

It need a lot of improvement before it would be useful.

To avoid this, it is necessary to right-click each page and send it to OneTab, which is high labor-intensive.

This extension is very useful for me that need to open many tab and collect information.

Não pede confirmação para remover todas abas atuais, para agrupar em uma aba/página com os links. Deveria ter essa opção de configuração, inclusive a confirmação para realizar esse processo de agrupar os links de abas em apenas uma aba DESTACANDO que as abas serão fechadas.

This extension makes tab management super easy. I have had all my tab links disappear before, but they have always shown up again with a refresh or a browser restart. To be safe though, I do export my tabs occasionally.
I especially like:
- ability to name tab groups
- ability to lock tab groups
- ability to quickly reopen a tab group
- when my tabs get out of control, I send them all to OneTab where they are much easier to pick and choose the keepers and then sort them
The only thing that is mildly annoying for me is that I will occasionally hit the OneTab icon in my toolbar by mistake and send all my tabs to OneTab. This is a very minor inconvenience though because I can restore all the tabs almost as quickly.

it's great and I've been using it for years, but it is missing a merge function whereby i can merge a list with another one

DO NOT INSTALL THIS. It will delete all of your tabs, with no way to recover them. Check the other reviews, this is happening to everyone.
