Firefox recommended a "Reset" of the browser, which created a "Old Firefox Data" folder on my desktop containing a backup of all of my profile data — including extension data. I have tried restoring my OneTab extension data (links/URLs) using Firefox's restoration process, but OneTab is the only extension that does not seem to restore its previous data. I have contacted OneTab through their form on their website twice and have not heard back. I would pay for support at this point, but it's unfortunate I am dealing with potential data loss with no answer from the developer. Again, I would compensate the developer to assist in helping my current situation. If I am able to restore the data, I will update my review and increase my rating.

Works on Firefox for desktop, but for Android, it just closes all your tabs and leaves you with an empty page. Unfortunately, Firefox can only restore the latest 10 tabs.

it would be so much better if it was like the chrome

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.

It's session manager and tab suspender all in one. It can also share saved web urls.

I am new with this ad and want like to know more about it

Please add a dark theme option

This is the closest thing I've seen to the "set tabs aside" feature from edge. Very helpful at putting all my tabs in one place to be seen easily. I highly recommend giving this a try.

Wow! I couldn't imagine more!

Lifesaver.
