Tab Router von Logan Grado

Tab Router keeps your browser windows organised by context.

When you open a link from outside Firefox (from Slack, email, a terminal, or anywhere else) Tab Router finds the window where you're
already working on that site and moves the tab there automatically.

Example: You have two windows open: one for gitlab.com/org/repo-A, one for gitlab.com/org/repo-B. A teammate sends you a link to gitlab.com/org/repo-A/issues/42. It lands in the first window, not wherever your cursor happened to be.

Matching is done by URL prefix, most-specific first. The window with the deepest match wins.

Links you open yourself inside Firefox — by clicking, middle-clicking, or using Ctrl+T — are left alone. Only externally-opened links are routed.
