This has become a Must-Have add-on for me.
Replaced my bookmarks toolbar as it just works so much better!
Wish I could give it 10 stars!

This creates so much spacetime

Great add-on. I didn't realized how much I needed it until I tried it!

no puedo vivir sin esto... me sirve para dejar cosas para más tarde

great addon but would it be possible to make it work on android?

Simply the best! Convenient. Reliable. Smart, and intuitive UI. Easy to use. Mad respect!

Update 2023-11-14 : I lost the entire OneTab content... several thousand URLs that I valued. 😔

Initial review :
Essential, perfectly effective, reliable, and ideally well designed!

This WAS absolutely great when it did what it was made for. Unfortunately, my onetab page has turned up empty and that means it isn't fit for its explicitly intended purpose.
Good idea, good attempt, but it's not worth trusting this add-on for anything more than casual usage.

This is one of the best add-ons for me as it saves me from having endless tabs lined up or copying each link into a draft e-mail that I never go back and look at. Now with being able to group, star and lock groups and links, as well as selectively save tabs, it takes a load off my mind and makes it easier for me to pick up a day or two later.

Works great.

Worst Add-on on Firefox (not necessarily applied to other browsers; maybe works well with others); it does not work at all; it won't budge a bit by reloading the expected one-page with all the tabs stacked.

I've long been a "multiple tabs open" person and this just makes life soooo much easier, not to mention dramatically reducing memory usage.
However, I too wish there was a FF Mobile version in the near future. I'd pay for that app!
Thank you!

love this. I often work on multiple projects at once and I use this to keep the sources I need organized and easily accessible.

So easy to use. Just what I was looking for.

很好！我想要的都有了

It works when it wants to. But randomly, even between sessions or reboots, it forgets the 400-odd tabs that had been imported or saved into it. It has done this multiple times on both Chrome AND Firefox, and I will be taking my volatile data elsewhere.
Good day.

Отлично.
1. Сделайте сворачивание групп.
2. Вы написали , что сделали изменение хранилища в мае 2018 года. Почем не написали об этом на странице расширения :) ? Мы боимся, что OneTab умер :(
