I will rate with 3 stars because addon developer created this addon. If mozilla made this add-on then I would rate it with 0 because it doesn't even deserve a rating of 1. I am still using Tab Groups because groups are totally hidden and I can backup all groups and tabs with just a few clicks. In less than 1 minute I have 100+ tabs on my laptop.

What I need to do is foud a developer, then pay him to hack Firefox version 54 and change it with latest firefox version.

Latest firefox versions is totally the same as any other browser -> GARBAGE.

100 tabs use only 1 GB of ram :D why do we even need x64 if browsers are NOT even created to run more than 10 tabs!!

Running 50+ tabs without Multi-row no thanks!! I will not have my tabs in second window, because Multi-row do the job perfect and I can see tabs names without clicking on anything!

I like browsing fast and with less clicks and not with more click to do the same!

For example new sidebar oh my good!!! By default sidebar on the left side and icon for open/close sidebar on the right side :D :D :D Every time moving the mouse on the entire screen :D do they even have brains??!

Excellent extension for most common browsers. Missing feature of a cloud sync ability so One Tab info was shared across browsers is what keeps this from being 5/5 for me.

~When I am researching something, I tend to open a lot of tabs. It gets chaotic and then, at the end of the day, I just don't want to see them any more. One Tab takes care of it, like a good housekeeper. Wonderful!~
Well that was from while ago. After a recent update, we went from 5 to 0 stars but 1 will have to do. No One Tab, it completely disappeared and with it, my tabs (obviously).

really useful, especially while running 10 on bootcamp and always peaking RAM levels (Thanks windows 10)

FINGER WEG!!!
Ein Klick auf Speichern hat bei mir sämtliche Tabs geschlossen, ohne eine Liste zu erzeugen. Alle Tabs waren somit weg. Die App sollte eher TrashTab heißen.

Buenisima

Not compatible with Panorama Tab Groups, Panorama View

I use this extension daily, thank you. One thing that i'd like to request that would make life easier is the function of the toolbar button. Either add another button for the function of "send only this tab to onetab" or add an option for function.

Like many others I tried it but it's disappointing.
My 100+ tabs are lost.
It seems that on Android there are two types of tabs, recently open (the one open on the current session maybe?) and older one (from previous sessions). The older one are not recognize by onetab, thus not recorded.

For me, this has become an indispensable extension. A special feature is the possibility to give a name to saved tabs. This increases the clarity. With OneTab, for example, I can save all open tabs for a thematic search with one click and restore them at a later time.
