Only after a while I realized how helpful this add-on is! I am using it now all the time.

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.

Дополнение рухнуло. Все сохранённые вкладки пропали.

WOW

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 This extension is no longer maintained - use at your own risk.

Excellent add-on that does exactly as it claims. Secure way to 'park' your browsing session before restarting your computer or making a collection of frequently accessed sites for easy browsing. Nice work guys, thanks for your efforts!

Es muy útil y todo, pero deberían cambiar la interfaz y más que nada hacer los enlaces al compartir duren más, por lo menos 1 semana.

Works great, I love this add-on.
My only suggestion would be to add a right click context menu option for OneTab once a specific tab is clicked, so that I don't need to have the icon constantly in my toolbar.
I feel like this used to be an option, but I don't see it anymore so maybe I was mistaken.

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.

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.
