Local Session Sync od artinski

Local Session Sync helps developers recreate authenticated browser sessions on localhost while working across dev, stage, UAT, and production-like environments.

The add-on copies selected cookies from the active tab to configured localhost targets, such as http://localhost:3000/. It only runs when the user invokes it and requests source-site access at runtime.

Features:
- Clear and sync localhost cookies from the active tab.
- Sync without clearing existing localhost cookies.
- Clear configured localhost cookies without copying from the active tab.
- Configure one or more localhost targets.
- Include or exclude cookies by name substring, comma-separated names, one name per line, or regular expression.
- Keep all cookie handling local in the browser.

The add-on has no backend, analytics, advertising, tracking, or external data sharing. It does not bypass authentication or authorization checks; it only recreates compatible browser cookie state on localhost for development workflows.
