TabVPN by SPYder4

TabVPN adds "Open with VPN" to Firefox's right-click menu. The link opens in an isolated container tab routed through a local Tor client, and only that link: the rest of your browsing is untouched. It is a per-link Tor proxy, not a full-device VPN.

HOW TO START

Install this extension.
Download and run the free TabVPN installer for your OS ([Windows / macOS / Linux]) from
https://github.com/lyapupastar-png/TabVPN/releases
It sets up a local Tor client and the bridge the extension needs. Without it the extension won't work.
Right-click any link → "Open with VPN".

FEATURES
• Per-link routing: only the link you choose goes through Tor
• Isolated container: separate cookies, sessions and storage
• WebRTC disabled inside VPN tabs to prevent real-IP leaks
• Automatic circuit rotation on 403 responses, with retry
• Cloudflare challenge detection: retries wait until you finish the CAPTCHA

WHY THESE PERMISSIONS
• Native messaging: to talk to the local Tor client
• Proxy: to route only container tabs through Tor
• Tabs / navigation / all sites: to open links in the container and detect 403 / Cloudflare pages
