Very High CPU usage on many tabs.
Other wise is amazing tools i am using all the time. because of this issue i have to disable it and enable all the time to avoid my CPU fan go crazy.

Garbage extension. Can not find specific previous session. UI absolutely terrible. I can not emphasize how much I hate this PoS software. Uninstalling.

神です。ありがとうございます。無いと困ります。

Cloud sync is broken, infinite loading (Same thing like GitHub issue 1451). Suggested fix to delete all data does not work.

May work well for local-only use. But extension explicitly advertises cloud sync feature.

Do not use this on browsers with multiple workspaces like Floorp - it moves all the tabs to one workspace, rendering the extension worse than useless.

The addon is not bad, at first glance. He copes with the assigned tasks, BUT very frequent begging for money (donations) is very annoying. I even started writing down the dates when the internal "thank the author" timer went off.

And I was just opening a window to clear saved sessions.

Can you add local support for the addon to remember spit view tabs? thanks

One of the best extensions I've installed. Simple, effective, and doesn't bloat the browser at all.

Thank you, wery much. for work. for life.

Better than Firefox's built-in backup, but unnecessarily complicated!
I don't see the point of many of the features. Unfortunately, there's no help section to clarify this.

From the volume of open issues and the lack of activity on Git, It looks like Sienori has either abandoned this extension or doesn't have the time to maintain it. April 26.

Auto-save doesn't work, hence data loss
