Duplicated sessions are a result of browser quitting without Tablerone saving changes made to a session. (Fresh unsaved session get logged in the Archive as “closed unsaved”.)
This happens because the browser restores session(s) on start-up, but the same tabs are now assigned to a new window with a different ID from the last time. Thus tricking Tablerone into interpreting it as a new session.
Unfortunately, the only solutions at this moment are:
- Delete older versions when duplication happens
- Move missing tabs from the new to old session to preserve tagging, favourite, and notes
- Be mindful about manually re-saving sessions before closing
We are reconsidering the current implementation and working on an improvement. We aim to bring the reliability of auto-saving combined with the power to manually control save over-rides.
