I have had some 120+ tabs open, many of them having its own history of a few pages visited. After using OneTab, I've lost the history behind each individual tab...

Simple and Easy to Use. Would be great if it can form trees

I don't ever want to go back to my life before I downloaded this. THANK YOU! It's so simple and yet everything a power user needs. 5 stars ☆

Extremely useful

I hate this add-on, because of this oneTab my unsaved code is lost. My two days work!

OneTab de OneTab Team

Disculpen, pero seria bueno poder ordenar los enlaces cuando estan en el onetab y poder marcar aquellos a los cuales uno cliquea para abrirlos en una nueva pestaña del Firefox

Excellent add-on, very effective and easy to use. It has never failed me. If you miss the dark mode, just use Dark Reader.

Monochromatic icon for dark and light themes are needed. Please some automatic backup should be there.

Шикарное дополнение! Работаешь ты с 100 вкладками. И тебе надо, что бы как то запомнились, во первых, все эти 100 ссылок разом. Во вторых, что бы в той же последовательности, как они у тебя открыты сейчас. Раз - нажал и всё. Удобно. Через пол года или год нашёл этот список ( ему тут можно дать имя), нажал на Открыть список. И вуаля! В общем, шикарное дополнение!
Вот только после очистки Firefox не могу найти, где вся ранее мной записанная информация за два года пользования мной этим плагином. Ищу с вчерашнего дня, не могу понять, откуда восстановить всё это. Два года коту под хвост!

Brilliant. I had 109 tabs open and I could not find a fast and easy way to move them to my new PC ... until I found this extension. Simple-as extension, pure gold in my case. Go, install it to see what it can do for you.
It looks scary at first as it closes all tabs and presents you with 1 page full with the URLs but you can easily restore. Or in my case export which is in txt format, then I wrote a draft email, opened the draft on my new PC, copy&paste into OneTab's import window, done. OneHappyDude :)

Is this open source? If yes whats the link?

This addon is very useful, but could there be option to not automatically focus to OneTab tab once browser is just started?

Why does Mozilla insist on keeping its pages as bright as the sun?
Please don't follow in their footsteps. This is a great extension but the white background is killing me here.

I'll (without hesitation) give this extension a 5-star rating since it makes the Firefox UX that much better, but give us some sort of dark background!
