Tabby

Save the current window's open tab URLs as a .txt list, reopen every link in a .txt, or open every URL found in selected text.

Tabby moves a window's tabs to and from a plain text file. Save every open tab in the current window as a .txt — one URL per line, nothing else. Drop that file back on Tabby later, or on another machine, and every link reopens. It also reads a selection: highlight any block of text on a page, and Tabby opens every URL it finds in it. Useful for a list of links in an email, a spreadsheet cell, or a chunk of docs. Two housekeeping actions round it out — sort the window's tabs alphabetically by address, pinned tabs left where they are, and remove every tab group at once without closing anything. No account, no options page, no sync, no telemetry. Nothing leaves your browser.
