THE VERY BEST. Just need a option to right click the tab(s) and "send to OneTab".

Нельзя отправлять по одной вкладке в хранилище

Superbe extrension permettant de faire nettoyage de tout ces onglets que nous désirons garder accessible, Bravo au concepteur!

Could be 5 stars if it had the option to disable context menu thing

ein ausgezeichnetes Add-On dass mir die tägliche Arbeit wesentlich vereinfacht!

Great. A bit clumsy in manipulating groups, but extremely effective in reducing FF crashes and slowdowns. Recent updates have solved several minor user interface problems.

Thank you for adding a dark mode.

Очень незаменимое дополнение особенно для тех кто ведёт много проектов одновременно

I cannot express my feelings when tabs that have been there for months, are gone after trying the restore all function of this addon. It failed to restore all the tabs and now they are gone. Several of those tabs where markers to particular links that needed to be checked periodically or something similar, now all except 15, the oldest 15 at that, remain.

Great Add-on BUT it stopped working several times and made the saved Tabs inaccessible.
No response from the developers. :((

This is my favorite extension for any browser. I was mad the first time it crashed and when I noticed the high CPU usage but the solution is to backup your URLs to notepad using export in onetab before you reach 400 and then remove them from one tab. They are easily imported/exported back and forth. With notepad you can save different files for each subject.

No longer working properly, used tons of CPU and memory while it's tab was open.

Restore all tabs not working

it lost my tab.
i have 400+tab ,when i add this addon to my firefox , it only get 100 tab . the others lost .
