It is good, but it needs still be improved...

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

Beautiful.. Except This is one of the best tab managers where I can save so many, tabs and be able to view them in a snap. Super organized. EXCEPT I am unable to use this as it stores private windows/tabs with all the others and reopens these private tabs into non private windows. Deal Breaker

Wish that when you onetab in private window/private browsing it doesn't open them back up in normal window/no-private one.

This tab icon is too ugly, I hope it can be replaced.

The only thing missing is the night mode, putting this is perfect

I just wish it'd use the Firefox sync functionality because I lose tabs every time I forget and fiddle with the Firefox installation. Otherwise 5 stars. Good job!

well done ....

very useful but the ui kinda sucks

I like the app, but there is a nuance.
I cannot select specific tabs and send them to OneTab, there is no "OneTab" item in the context menu of the tab. I have to move the group of tabs to the end, select the previous one, right-click on the add-on icon and select "Send tabs on the right...". Very uncomfortable.
