It is a mess, and was added without my approval! Don't make changes without making them easy to use.

all tabs gone - no chance to restore

even if this saves RAM, it CPUfloods more than its worth

Tabs will be restored without its tab histories. I would not have even given it a try if only I had known this before. Very disappointed.

missing date at frequently

I lost all my tabs when restoring them from the page.

OneTab lost all my tab data many times. I thought that maybe automatic upgrades/updates on Firefox may have been the culprit, but having just reinstalled it for the first time in a while, it immediate lost many windows of data for me, IMMEDIATELY after clicking on bring all windows into One Tab. Thanks, One Tab.

The functionality is good; however, the irritation factor is over-the-top. When I start my browser, OneTab presents itself every time regardless of what I choose as my home tab. Yes I know OneTab is there; I don't want it in my face when I don't need it. The functionality is not worth the aggravation.

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 This extension is no longer maintained - use at your own risk.

OneTab has been working nice for me for years, but a couple of months ago it just stopped working. I can send tabs to onetab but the directory won't show, so I don't have access to ANY of the tabs I have been saving for YEARS.

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

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!

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

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.

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.

400% CPU peaks, database corruption and Tabs loss. app Javascript Freeze the browser. No updates or maintainance in a whole year. Zombie addon, in search of a replacement.

I lost all tabs... again

una mierda

At pressing "Restore all" bad things happen:
- Locked tabs are lost;
- Some not-locked tabs are lost, too;
- Some tabs are re-open in new windows rather than new tabs;
Firefox 62 (64-bit)

After using it for months/years, I lost a whole lot of unrecoverable tabs.
With no warnings at all, yesterday it deleted all my tabs information and now I can't recover it :(
To quote another user: "Second time I am losing a whole lot of unrecoverable tabs.
And usually when I don't like something I just uninstall and move on with my life. But this time is different.
I feel like I have to WARN people because OneTab fails to do so. If you have a sub-par extension, either fix it(automatically backup? support recovery?), take it down or include a Disclaimer that your extension should be used only for casual usage.

Because anyone who actually wants to keep their sh*t should definitely STEER AWAY from this extension."

useless....

I lost all my tabs after launched this extension.

links' icons are broken.
If a lot of tabs saved, loading onetab page is slow.
It would possibly lost all of saved tabs.

And now there's an better alternative (and is FREE SOFTWARE)(and don't require "Access your data for all websites").

EDIT 12/24/2019:
Can't work on Firefox Android at all, all my opened tabs lost but only that poor 1 is saved!! If you can't do it, then don't make it available on Android platform!! What a garbage
