## Description

**SealSkin Isolation** lets you open files and URLs in secure, isolated environments powered by containerized desktop applications. The self-hosted client-server platform streams applications directly to Firefox, helping separate potentially risky content and workflows from your local browser environment.

The extension can intercept browser actions such as link clicks and redirects, sending them to an isolated application environment on a remote server. SealSkin supports end-to-end encryption and requires a server component with a legitimate SSL certificate installed in `/config/ssl`. Deploy the server using the [SealSkin Docker project](https://github.com/linuxserver/docker-sealskin).
