How do I install Not F3?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does Not F3 work with?

The listing gives Minecraft 1.21.10, 1.20.1. This is the version stated by the author or source site, not something we verified ourselves.

Not F3

Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.

by NaViHacker · on CurseForge

NoF3 is a mod that completely disables the F3 debug screen. Ideal for RP servers and builds where coordinates and debugging are considered cheating…

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

ChatGPT сказал:

NoF3 is a simple client-side mod for Minecraft 1.20.1 (Forge) that completely disables the F3 debug screen.

The mod is made for players on RP/survival servers who don’t want others to use the “cheaty” features of F3: coordinates, FPS, biome info, chunk data, etc.

After installing NoF3:

Pressing F3 no longer opens the debug screen.
All debug information stays disabled.

The mod works client-side only and does not need to be installed on the server (and the server cannot force players to use or remove it).

This is a convenient solution for those who:

Run RP servers where players are not allowed to see their coordinates.
Build hardcore modpacks where the player should navigate using the world itself.
Want to remove unnecessary debug information and keep the interface clean and immersive.

Features

🔒 Completely disables the F3 debug screen.
🧠 No settings or configs — install and forget.
🧩 Works on Forge 1.20.1.
🎮 Suitable for both singleplayer and multiplayer servers.
