Incredible usefull update of the previous 'OneTab.' Like, the share as webpage option- creating a html overview of the saved tabs (including QR-code for easy sharing). Not to mention working with groups, pinned-tabs and so on... I absolutely <3 it!

I can quickly save and close multiple tabs, freeing up resources, speeding up my computer, and saving tabs I want to use in the future. Awesome.

Lost all tabs randomly. I followed guides posted by the devs to recover, but didn't work. I loved this app, but I can't use it anymore after this has happened twice in 3 months. You are better off making a bookmark folder and organizing you tabs in that as it's much safer.

FirefoxはQuantum以降複数タブでのパフォーマンス上げる用になったので当然メモリ使用率あがったのでOnetabの重要製がマシました。
私は大体30くらいタブ作るんですがそうすると余裕で1gb以上は使うのでこいつで管理すれば元のメモリ大体500ｍｂくらいになります。

One of my four essential Add-ons. Losing OneTab would seriously affect my productivity!

I love OneTab, it constantly saves me from Tab Adiction...

ADDED ON MY MAC!!!!!!!!!! AT LAST!!!!

This helps organize my tabs while saving memory. It really works.

Moved to Firefox from Chrome. My old App (Tab Cloud) was not supported so I moved to One Tab. I am happy with the app, Had a small learning curve as I lost all my saved Tabs when I restored them. Found the options page and made some changes so this no longer happens. A very fast app that gets my mornings started off with all the web sites I check each day. I recommend One Tab.

great

Great extension ! Very useful and easy to use !

OneTab stopped working after I upgraded to Firefox Quantum. Now all my links are lost. I have a backup of my hard drive from before i upgraded to firefox quantum but can't find any documentation of where onetab data is stored. how do i restore from my backup and recover the few hundred links i had in onetab?

Highly Recommended!! Does Exactly what it promises... simple & effective. Love it!

It worked great until I collected about 25 000 tabs in total.
Now I can't properly open OneTab page with saved tabs because it takes too much time to load.

Better approach - just bookmark all tabs to some folder and close all of them (FF has bult-in functions for both tasks),
It works fast and you can sync your saved tabs using any bookmark sync addon (there are many of them).

This add-on will be much better if:
1) It doesn't open one page with ALL saved tabs (too slow!)
2) It [optionally] uses bookmarks for storage (free sync and other stuff)
