wtf is firefox-xx?

This project, known as firefox-xx, is a ready-to-use bundle that combines the Firefox web browser with built-in tools to bypass internet censorship. It's designed for people in places like China where many popular websites are blocked or restricted. Instead of figuring out how to set up a separate proxy service and configure a browser to work with it, you get a single package that handles everything for you, what the project calls a "lazy person's censorship circumvention package." The way it works is straightforward. You download a roughly 60-megabyte file, unzip it, and click a single launch script. On Windows 7, 8, or 10, it will ask for administrator permission to install a security certificate, which is needed for the proxy connection to work properly. After that, Firefox opens already configured to route traffic through XX-Net, an open-source tool that finds available connections to relay your browsing. The first launch takes about ten minutes because the tool needs to scan for enough working server addresses before browsing becomes smooth. The target audience is anyone living behind a firewall who wants access to blocked sites without technical hassle. A journalist who needs to reach international news sources, a student trying to use Google for research, or really anyone who wants to visit websites their government has filtered out would find this useful. The project explicitly aims to help beginners by including 200 pre-configured connection points and automating most of the setup that would normally require following a multi-step tutorial. A few things stand out about how it's built. The whole thing runs as a portable app, meaning it doesn't install permanently on your system and you can run it from a USB stick. It also enforces a single process, so accidentally opening it multiple times won't create duplicates. The project bundles an older version of Firefox (45 ESR), which is a deliberate tradeoff, older versions were more flexible about third-party plugins and extensions, which this setup relies on. The README notes that Windows XP users need an additional patch, and download speeds may be slow since the hosting service itself is affected by the same filtering the tool is meant to bypass.
