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.

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.

Works well on desktop. Does not work on mobile -- it closes tabs without saving them.

Ok, at first I wrote a negative review but on a second try it seems to be working fine, once I got the hang of it.

Will add more after some use. On another droid I often wind up with 50-60 tabs open, which gets kinda slow and uses lots of memory, so this will be really handy there.

cheers

I *highly* recommend this add-on. However, since a recent Firefox update it has crashing my browser when I click the OneTab button.

This is with Firefox 68.0.1 on Linux.

Please help me I lost all my tabs but I found the file storage.json.migrated which contains all my tab data. I can't use this to import it into OneTab

Why is this permission required?
"Access your data for all websites"

The Firefox docs mention that: "The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords."

This addon's extremely useful to me but I find the use of that permission unnerving.

DO NOT UPDATE TO 1.26, I LOST ALL MY TABS! 💣

Downgrading to 1.25 solved the issue

Мне очень нравиться Ваше приложение. Но я столкнулся с такой проблемой - не могу найти и скачать OneTab 1.23 для Firefox 56, чтобы перейти на Firefox 57 и выше. Не могли бы вы дать ссылку на OneTab 1.23.
Как только перейду на Firefox 57 и выше, поставлю Вам 5 звездочек.

I really like your app. But I ran into such a problem - I can’t find and download OneTab 1.23 for Firefox 56 to upgrade to Firefox 57 and higher. Could you give a link to the OneTab 1.23.
As soon as I switch to Firefox 57 and above, I’ll give you 5 stars.

Дополнение рухнуло. Все сохранённые вкладки пропали.

It works as advertised until the browser updates and then you lose all the tabs/links.

Let me choose the behavior of the toolbar button. I want you to send only the active tab only to one click. Thank you.

1. It is easier to use than bookmarks because the user can slide links around quickly.
2. By using the import function users can create new groups
3. I use a sandboxed browser (sandboxie.com) and I would like to see changed is to add the ability to export all URLs to a text editor and retain the group names, so when I empty the sandbox and restart the browser I don't have to manually put in group names again. I do this manually (export, copy, paste into a Text file), but it is not as
productive a method.
4. It would also be nice if the options settings could be retained instead of having to reset them each time after deleting the sandbox contents.
I haven't seen any changes for a lon?g time so why are we asked to make recommendations

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.

please add the sync function and make it compatitble with firefox mobile version.

Ok being a dummy it's informative

very good

Pretty good, functional, but I wish I could sync my One-Tab lists across different devices for which I'm logged into the same Firefox account.
