Tab Saver saves the tabs from your window as a named group and, if you ask it to, closes them only after every tab is confirmed saved. No account, and nothing leaves your browser.
Add Tab Saver, it's freeThere's an easier way
const tabs_closed_before_saved = 0;
Every tab is written to storage and read back before a single tab closes. If the write fails, your tabs stay open.
No account, no sync, no analytics. Your groups stay in the profile they were saved in unless you export them yourself.
Closed the wrong set? Undo reopens the tabs from the last save that aren't already back.
A session manager "saved" a weekend of sorted tabs and then dropped them in an update. Third time something like that happened. So this one checks the save actually worked before it closes anything, keeps everything in your own profile, and lets you export the lot as plain JSON so a backup is always one click away.

Nothing closes. The popup shows the error and your tabs stay exactly where they were.
Five groups on the free plan. Unlimited removes the group limit for $15 once. Either plan has about 8 MB of local storage, so export and delete a group if you run out.
