Anti Firmanent
Privacy in Minecraft is often an afterthought, but for many players, it is the deciding factor in how they play. The Anti Firmanent add-on tackles a specific and invasive issue: the ModAnnouncer packet sent by the Firmament mod. This packet broadcasts your entire mod list to the server, revealing every single mod you have installed. For players who value their anonymity or simply do not want a server to know their full setup, this is a dealbreaker. Anti Firmanent steps in to block that packet, giving you back control over what you share.
Firmament, a popular client-side mod, attempts to send this announcement when you join a server. It is not standard Fabric behavior. In fact, only Forge has a built-in mod announcer, and the creator of Anti Firmanent sees no reason for one to exist in Fabric. This add-on is a direct response to that unnecessary data leak. It does not break the game, it does not interfere with other mods, and it does not require the server to have anything installed. It simply filters out the packet before it ever leaves your client.
Why You Need Anti Firmanent for Minecraft
Think about what your mod list reveals. It shows the server administrators exactly which client-side enhancements, performance mods, or utility tools you are using. This information can be used to target you, restrict your access, or even ban you for using mods the server does not approve of. The Anti Firmanent for Minecraft ensures that this data stays on your machine. No server should require access to your mod folder, and no single mod should be sending this information out without your prior consent or knowledge.
The philosophy behind this add-on is simple: transparency and consent. The developer explicitly states that no server is required to see mod IDs. By blocking the ModAnnouncer packet, you are enforcing that boundary. This is not a hack or a cheat; it is a privacy tool. It works quietly in the background, and you will not even notice it is there until you realize a server no longer greets you with a list of your mods.
Key Features of Anti Firmanent
- Blocks the ModAnnouncer packet from Firmament.
- Works entirely client-side; no server-side installation needed.
- Lightweight and does not affect game performance.
- Open source under the MIT license, so you can review or modify the code.
- Compatible with Fabric, supporting Minecraft versions that Firmament targets.
How to Install Anti Firmanent
Installing this add-on is straightforward, especially if you are familiar with Fabric mods. First, ensure you have the Fabric Loader installed for your specific Minecraft version. The add-on supports the same versions that Firmament does, so check the official mod page for the exact list. Once your loader is ready, simply drop the Anti Firmanent jar file into your mods folder. That is it. There is no configuration file to edit and no in-game menu to navigate.
For those who prefer a more streamlined approach, the foxygame.net launcher simplifies the entire process. Its add-on catalog includes Anti Firmanent, and you can perform a one-click install directly from the launcher. This eliminates the need to manually download and move files, making the setup even faster. The launcher also handles version compatibility checks, so you will know immediately if the add-on works with your current Minecraft setup.
Step-by-Step Installation Guide
If you are doing it manually, follow these steps:
- Download the latest Anti Firmanent jar file from the official source.
- Locate your Minecraft game directory (usually
.minecraft). - Open the
modsfolder. If it does not exist, create it. - Move the downloaded jar file into the
modsfolder. - Launch Minecraft with the Fabric profile.
After these steps, the add-on is active. You do not need to do anything else. The packet is blocked automatically every time you join a server. If you ever want to verify it is working, you can check the logs or simply observe that Firmament's announcement no longer appears in the server chat.
Compatibility and Loader Support
Anti Firmanent is built specifically for Fabric. It does not support Forge or Quilt, so make sure you are using the correct loader. The add-on is updated to match the latest Minecraft versions that Firmament supports. This ensures you can use both mods together without any version conflicts. The developer maintains the project actively, so you can expect updates whenever a new Minecraft version is released.
For users of the foxygame.net launcher, version compatibility is handled automatically. The launcher's integration with Anti Firmanent means you can switch between different Minecraft versions and the add-on will be adjusted accordingly. This is particularly useful for players who play on multiple servers with different version requirements. The launcher also provides auto-updates, so you never have to worry about manually checking for a new release.
Open Source and Community
The developer of Anti Firmanent has a unique stance on licensing. The code is open source under the MIT license, meaning anyone can use, modify, and distribute it freely. The developer even jokes about the permissive nature of the license, stating that they do not care if you "skid" the code multiple times. This openness encourages community contributions. If you find a bug, you can fix it yourself and submit a pull request. If you prefer, you can also open a GitHub issue to report problems.
The logo is a derivative of the Firmament logo, modified with an X over it to convey that this add-on blocks something from Firmament. The original logo is licensed under CC-BY-4.0, and the modification is intended as a clear visual indicator of the add-on's purpose. The original authors and contributors of FirmamentMC do not endorse this project, and the developer explicitly states there is no intent to tarnish their reputation. It is simply an easy way to communicate the add-on's function.
Final Thoughts
Privacy is not a luxury; it is a right. The Anti Firmanent add-on restores that right for Fabric players who want to keep their mod list private. It is a small, focused tool that does exactly what it promises. Whether you download Anti Firmanent manually or use the foxygame.net launcher for a seamless experience, you are taking a meaningful step toward protecting your data. The installation is quick, the impact is immediate, and the peace of mind is invaluable. If you play with Firmament and value your privacy, this add-on is a must-have.
In a world where data collection is rampant, even in games, having the option to opt out is crucial. Anti Firmanent gives you that option. It does not ask for permission; it simply enforces your right to privacy. So, take control of your Minecraft experience today and block that unnecessary packet. Your mod list is your business, and no server should know it without your say-so.
