Лучшее в своём роде. Главная фича - складывать вкладки в список на потом. В отличии от закладок сохраняет порядок и группы вкладок. Очень удобно.
Но почему-то на Mac не устанавливается.

I'm a person who opens up many many tabs, at the end of the day I see that I didn't have time to go through all of them and I have to either bookmark or crash Firefox so that it restores it for me the next time I boot into my computer; however those options are either time-consuming or unreliable.

OneTab is the perfect plugin for me, I hope they keep this plugin on Firefox forever.
I save all my tabs with one-click, very easy and useful, then they are conveniently and neatly sorted into groups, based on when you saved those tabs, you can also arrange them into groups and name them, you can restore tabs individually or all at once, also you can export/import the tabs that you saved.

It's everything I've ever wanted for such a plugin, great job and thanks to: the OneTab Team, the developers, and all those people that made this possible.

Exactly what I needed, with some cool extra features I had not thought about. It's a very good tab manager to bounce all your tabs down to one webpage, save them, export them, share all tabs as a URL, etc.

Best addon! Opens suspended tabs as well, even after pc restart!

It's just the best extension for your browser. Unavoidable ! Great thanks to the team :-)

It is really convenient and is one of the best apps I have used.Being able to open as a web page link you can easily share with others

Li análise anterior, de 2015, e o problema se repete: o OneTab perde todos os dados de links que armazenamos nele. Do nada, um belo dia, os mais de 600 links somem. Mas nem tudo está perdido, se você exportar seus links regularmente, para um arquivo de texto com nome mais ou menos assim: OneTab 20180711. Se você não usa janelas privativas, pode recompor seus links acessados usando o histórico. Mas se quiser usar o OneTab para armazenar seus links de abas privativas, precisará exportar os dados do OneTab antes de sair do Firefox. Então, em caso de perda de dados da extensão, basta fazer o processo inverso, importar do arquivo que você gravou. É sempre conveniente lembrar que o OneTab é agil, mas não foi projetado especificamente para guardar toda uma base de histórico de links.

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!
