🚨 Is Facebook Eating Your CPU? Here's How to Fix It

Ever noticed your CPU spiking or your laptop fans screaming when you have a few Facebook tabs open in Google Chrome? You’re not imagining things. Facebook is one of the heaviest websites on the internet — constantly loading videos, running background scripts, refreshing chats, and pushing real-time updates.

But don’t worry — here’s a simple, practical guide to reduce Facebook’s CPU usage dramatically without giving it up.

🔍 Why Does Facebook Use So Much CPU?

• Autoplay videos in your feed run even if you're not watching.

• Background scripts keep updating notifications, chat, and more.

• Multiple open tabs = multiple processes draining your CPU.

• Heavy posts with lots of media or comments slow everything down.

✅ How to Stop Facebook from Burning Your CPU

1. 🚫 Turn Off Video Autoplay

This one change can drastically lower CPU usage:

• Visit Facebook Video Settings

• Set Auto-Play Videos to Off

---

2. 📱 Use the Mobile Version of Facebook

The mobile version is way lighter:

• Go to https://m.facebook.com

• Bookmark it if it works well for you

---

3. 🧩 Use a Content Blocker (uBlock Origin)

Block unnecessary scripts and background tracking:

• Install uBlock Origin

• Works on Chrome, Firefox, Edge and more

---

4. 💬 Disable Chat and Notifications

Live chat and browser notifications use a lot of CPU:

• Turn off Active Status in Facebook Messenger

• Disable Browser Notifications in Facebook settings

---

5. 🧠 Use Chrome's Built-in Task Manager

• Press Shift + Esc in Chrome

• Identify which tabs are using the most CPU

• Close tabs with heavy posts, live videos, or long comment threads

---

6. 🧪 Advanced: Block Background Scripts on Facebook

In uBlock Origin, go to Dashboard > My Filters, and add:

scss
 
facebook.com##+js(nostif, Notification, requestIdleCallback)
facebook.com##+js(aopr, setInterval)
facebook.com##+js(aopr, setTimeout)

⚠️ Use with caution — this may break some features (like chat or notifications).

7. 🦊 Try Another Browser

Some browsers handle Facebook better than Chrome:

• Firefox and Brave often use less CPU for the same content.

---

✅ In Summary

Facebook can be a real CPU hog — but with a few smart tweaks, you can make it much lighter. Whether it's disabling autoplay, switching to the mobile site, or blocking background scripts — your computer will thank you.
