I used this for Chrome and since I switched over to Firefox I need to have it. This a very handy app.

The one-click feature is nice as well as releasing the memory and cpu resources required to keep tabs open. The management is ok, i can work with it. The one downside to this is losing your backward/forward history. I was on the fence between 3 and 4 stars but I decided to give the developers the benefit of a doubt.

Awesome addon to save your work and resume a whole set of tabs

Amazing! Easy to use and the best part is it saves my tabs even if I close the browser

OneTab is now in dark mode. I am not sure whether its caused by any updates, FF theme, or FF updates. But, it's great.

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

I love this App! It has helped me make Firefox so much easier to manage!

I can't live without this extension and use it way more than bookmarks. It's easy to get carried away, but that's testament to how easy it is to save sites for later.

all tabs gone - no chance to restore
