The extension consumes all RAM and makes PC unusable. With 100 tabs on the list (closed) and 2 open tabs it eats all 8GB and all disk swap. Giving the fact the goal of extension is to save RAM, this makes no-sense.

Have been a onetab user for years at this point, and will be for years to come! :D

Great addion :)

Great features, easy to use, simple and effective

It is restoring tabs, one by one, so when I had 5600 tabs, it was trying to restore (open) a 5600 tabs one by one.
Browser of course crashed, so I was not able to open my tabs.
It is not possible to make "auto groups" based on domain or regular expression.

Some people here are idiotic (the ones who store 10 years long tabs history and never backup it). This extension is holy grail. IT WORKS GOOD. AND HAS NO ADS. FOR YEARS. Princesses who can't backup your sh#t once in a month are meant to suffer in this society. Thx mr developer. The only suggestion is to add star icon for bookmark saving in the tabs list

I exported my tabs from the Brave extension to come to Firefox (well, Zen), and it didn't export the names of my groups. This isn't a big deal for me, except sometimes I've put videos in their with the tab name as the timestamp, so of course that's gone. It's not like,,, horribly confusing or whatever, just extremely limited I guess. And I also lose the add date of the info.

DANGER. The app slows down the system a lot. And if you use groups for tabs, it deletes them!

ОПАСНО. Приложение сильно тормозит систему. А если вы используете группы для вкладок, то она их удаляет!

This is by far one of my favorite add-ons - cleans up your browsing experience, saves on ram, and you still have access to get at old tabs. Awesome!
