About this Mod
MCEF (Minecraft Chromium Embedded Framework)
MCEF is a mod and library for adding the Chromium web browser into Minecraft. This mod does not do anything useful by itself; it is a library for other mods to use the Chromium browser.
MCEF is based on java-cef (Java Chromium Embedded Framework), which is based on CEF (Chromium Embedded Framework), which is based on Chromium. It was originally created by montoyo. It was rewritten and currently maintained by the CinemaMod Group.
MCEF contains a downloader system for downloading the java-cef & CEF binaries required by the Chromium browser. This requires a connection to https://mcef-download.cinemamod.com.

Does MCEF (Minecraft Chromium Embedded Framework) need to be installed on the Minecraft server?
No. Modrinth marks MCEF (Minecraft Chromium Embedded Framework) as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does MCEF (Minecraft Chromium Embedded Framework) require?
Use a file for fabric, forge, neoforge and your exact Minecraft version. Supported versions include 1.21.4, 1.21.3, 1.21.2. Files for different loaders are not interchangeable.
MCEF (Minecraft Chromium Embedded Framework) is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
