I lost all my tabs once a while ago due to extension crash in Chrome. But I love this cool add-on and since moving from chrome to FF I'm glad that I can have it on FF, too !

Currently broken, FireFox updates DELETE the saved data. Same issue on Chrome, addon seems abandoned.

This is seriously a life saver when it comes to organisation. As a student, I work on different many different projects and assignments. I can keep each assignment in a different window, then send the entire window of tabs to OneTab when I am working on a separate assignment. Without OneTab, I would have windows cluttering my dock which would distracting me and suck up computer power.

I also really like that you can name and share tab groups. Sharing tab groups comes in very handy when I am using more than one computer to work on an assignment.

It's just great! Very easy to use and really efficient.

The entire add-on disappeared, along with over 600 saved tabs. No warning, and when I try to reinstall or find my lost tabs, there is no help. I've submitted a help email 3 times and have gotten no response. Firefox or OneTab - doesn't matter who is at fault - it doesn't work!

Sorry to burst your bubble Perce-Neige, but OneTab most definitely does lose the tabs. I've been using it for a couple of years, and have gone though multiple crashes with no problems -- until today. Firefox crashed, and when I started it back up OneTab was empty. This is unacceptable! OneTab should make a backup when Firefox closes (not crashes, but closes), and it should NEVER overwrite a file, even if corrupt. Two stars, and looking for a replacement.

Used this for a long time, then it lost all my bookmarks. Don't use.

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

Really great extension will be perfect if it gets nocturne or dark mode

2023 - OneTab no longer works in my Linux/Firefox environment. It's slowly disappearing off of each of my machines. I'm very sad.

Original Review
I'll admit it, I am VERY guilty of saving multiple tabs for 'later': Google Calendar, Outlook, YouTube, that website with an interesting article, something I found on Amazon . . . . Before you know it, I've multiple open tabs. I've only been using OneTab for about an hour now and am already finding that it's the answer to my 'Tab Mania'. All my tabs are there, ready and waiting and I've even set up a starred, saved tag I've labeled 'Usual' which is stuff I want all the time. So far, looking good!

OneTab lost a whole group of tabs, not for the first time. This extension is no longer maintained - use at your own risk.

I've had this extension for Chrome and Firefox. All my links have disappeared.

But doesn't matter what we write on the reviews.. They don't give a shit. They have never answered. Definitely removing OneTab. Has been an issue for a while and they still not doing anything about it.

Will be so easy to make a way to backup them automatically... but they don't care about people loosing all their work.

The only way I found to kind of keep a backup is saving every end of session as "share all as web page" even if you delete the links from the extension that saved bookmark will keep them. But you have to do it manually.

However, I'm just removing the extension. The devs don't give a shit about the users.

It works great for me. I tend to wind up having several tabs open because if Im on a site and there is a link, I'll open it in another Tab so I don't lose my place on the original site. When I notice any lag at all, I just send them all to OneTab and then select the tab I'm on at that time, then work my way back to the original page. It works quickly and I notice an immediate increase in speed and decrease in latency.

OneTab destroyed all my saved links in the past (about 2k links for 2 years) without any notice. When I look for old links, it's emptied. I've looked for store.js (json) as their information form OneTab websites, it's gone, the store.js file in browser-extension-data was disappeared too.
Avoid use this extension to prevent your pain.
CAUTION: They didn't update this extension for 1 year.
