Tab'o'mat URL to Window Router от superyaro

URL-to-Window Router keeps related tabs in the right Firefox window. It is useful when you work on multiple topics or projects in parallel and want external links to land in the window that already contains the matching project, service, or domain.

When a new HTTP(S) tab opens, the add-on checks existing windows for matching domains or configured routing rules, then moves the tab there.

It does not change URLs, redirect requests, reload pages, or transmit data. It only moves tabs inside Firefox.
