How to Enable WebGL in Firefox

  • Verified

    • Having trouble launching a simulation? It might be because WebGL is disabled in your Firefox browser. This guide will walk you through how to check, enable, and troubleshoot WebGL so everything runs smoothly.

    🧠 What is WebGL?

    WebGL (Web Graphics Library) allows your browser to render 3D simulations and graphics — essential for running Interplay Learning simulations.

    If WebGL Is Not Working...

    Step 1: Update Firefox

    Make sure you’re using the latest version of Firefox. WebGL is typically enabled by default in up-to-date versions.

    Step 2: Try a Different Browser or Device

    If updating doesn't help, try another supported browser (like Chrome, Edge, or Safari) or a different device. See our Supported Browsers.

    Step 3: Enable Hardware Acceleration in Firefox

    1. Open Firefox.

    2. Click the menu icon (☰) and select Settings.

    3. Under the General tab, scroll to the Performance section.

    4. Make sure “Use recommended performance settings” is checked.

      • If it’s unchecked, manually check “Use hardware acceleration when available.”

    Step 5: Inspect WebGL Status

    1. In a new Firefox tab, type: about:support

    2. Scroll to the Graphics section.

    3. Look for WebGL 2 Renderer:

      • ✅ If it shows your graphics card (e.g., “NVIDIA GeForce GTX 1050”), WebGL is enabled.

      • ❌ If it says "Blocked" or lists driver issues, your graphics card or driver may be unsupported or blacklisted.

    🔄 Update Your Graphics Drivers (if WebGL is still blocked)

    Make sure your video drivers are up to date. Click your graphics card brand to visit the official driver site:
