Seen a lot of critics of this but for me, at least, is working flawlessly.
I was far from my desktop for 3 months and had around 30 tabs stored, in 4 different groups. Now I'm back and my tabs are ready to be worked on again

It would be much better if there is a setting to change the default behaviour of the main button to just save the current tab instead of all tabs. I never want to save all the tabs.

People give one star ratings for the dumbest reasons and often down to user error. This addon is an awesome alternative to bookmarking or keeping tabs open that you plan to check out later. Used it for months without issue.

В Firefox команда "восстановить все" открывает все в новом окне... прошу прощения, настройки находятся во вкладке со списком группировки...

Lost my 83 tabs when I clicked "restore all".

Closes the tabs and stores the URLs. Breaks sites like Pandora.com

Despues de un un reinicio del ordenador por fallo del suministro electrico se ha perdido todas las pestañas guardadas en OneTab, no hay ningún backup no forma de recuperarlas.

I love this extension until I lost all my saved tabs suddenly…
shit extend！

Awesome. Focused solution and does what it sets out to do very well. Only wish is to be able to set a custom NewTab background color in settings.
