  • Insights uses the same filters: containers, age buckets, top domains, and duplicate URLs.
  • Active chips summarize search, filters, duplicate URL, and non-default view settings.

Selection and Export

  • Click a row or use the keyboard to set the active tab. Double-click opens it.
  • Select tabs with checkboxes or x. Use Shift x for a contiguous range.
  • The bulk bar can open selected tabs, copy URLs, copy Markdown, or copy OneTab format.
  • Export JSON downloads a reloadable snapshot with favicons. Drop it back in to reload later.
  • Right-click a row to open, copy URL, copy title, copy Markdown, or filter by domain.
Tip: Command searches the current filtered results, so it works as a fast jump list. The last loaded tab list, favicons, and preferences are saved locally in this browser for refresh/reopen.

Load your Firefox tabs

Review a Firefox session locally. Your files stay in this browser.

Drag your Firefox session files here Drop recovery.jsonlz4 and, optionally, containers.json from your Firefox profile folder.
Firefox tip Dragging a whole profile folder can crash Firefox and is slow in every browser. Pick or drop just the two session files instead: recovery.jsonlz4 (inside sessionstore-backups/) and, if you use container tabs, containers.json.
  1. Pick session file
    recovery.jsonlz4 (or previous.jsonlz4 / sessionstore.jsonlz4)
