OneTab has been one of my favorite addons for a few years now. It's simple, easy to use, and always maintained. I highly recommend it to anyone who needs to organize tabs and keep them for later, or even share them with someone with just one click.

Love this extension! It finally allowed me to stop saving temporary links to my bookmarks or notes and cleaned up my browser. I use it every day! The development team behind the extension is great, very responsive to any problems or bugs (which are rarely the case). It's a must have for everyone!

Great app, always being maintained, they had a bug for a few days and quickly fixed it. They get back to you when you contact them, and are constantly working on adding new features.

Really great tool if you want to keep group of tabs that you want to open and close together (e.g. a group of tabs for work, a group of tabs for studying, a group tabs when playing, etc...). Really appreciate the devs for rolling out the update on the usability issue on firefox.

Honestly this addon has been a life changer for me. It's almost as valuable as uBlock Plus imo.

I've had it for a long time now and the only issue I've ever experienced with it was this past weekend, but I emailed support about it and they were quick to put out a fix and give me an update on the situation.

I really hope people update their reviews because they couldn't wait a couple days. Because this extension is totally worth it.

A must have addon for tabaholics like myself.

There's only 3 things missing in my opinion:
* The ability to merge 2 windows sent to OneTab
* The ability to undo removing a tab inside OneTab
* Firefox (but not any Chrome based browser) always unpins the pinned OneTab on browser restart.

Secular Simplicity, love it. For those with inaccessibility issues after each/any Firefox patch/update, simply remove and reinstall the OneTab Extension; no complaining required.

Helps me to clean the unused tabs safely. However, the toolbar button is very easy to misclick. Perhaps it should ask for confirmation or open an action menu?

This is the best tab management tool. Everything else is over-complicated.

Desde la última actualización, funciona mal constantemente. A cada rato debo entrar a complementos para desactivar y volver a activar la extensión porque desaparece de la barra.

Randomly OneTab was not visible in the toolbar. All my links were gone! It's a great tool but not very reliable..

Worked great. In the last month stopped working. Today lost all my tabs I had been curating. I will never use another tab manager that doesn't allow me to sign in to restore tabs in case of problems.

great add-on, ... until I lost all my tabs

I know it is probably not a fault of OT devs, but as you may have noticed, it breaks over time.

OneTab is essential. However, as of Sep. 2020, it has a new bug: it disappears after the browser is launched, and you have to disable and re-enable to make it work. They need to fix this. Also, the developer could make it so much better, for example by allowing more ways to manage and display the tab list.
