Firefox 147 is available with smoother video, faster loads, and more control. The update not just includes bug fixes. There are some legit performance buffs, especially if you care about smooth video playback, faster page loads, and better control over your setup.

Big Win for AMD Users

If you are running an AMD GPU, this one’s for you. Firefox 147 introduces zero-copy video playback on systems with hardware decoding. Translation? Smoother videos, less overhead, and performance finally on par with Intel and Nvidia rigs. No more feeling like you’re playing on low settings while everyone else is on ultra.

Apple Silicon Gets a Boost

Mac gamers and power users aren’t left out either. WebGPU support is now live on Macs with Apple Silicon, unlocking better performance for next-gen web apps, browser games, and GPU-accelerated content.

Picture-in-Picture, But Smarter

Close a tab with a video running? Firefox can now automatically pop it out into Picture-in-Picture mode, so your stream, guide, or tutorial keeps playing while you move on, perfect for multitasking between matches.

Faster Page Loads = Less Waiting

Firefox 147 adds support for compression dictionaries, a new web standard that cuts down data transfer and speeds up page loading. Several major websites already use it, which means less loading, more doing.

Security Patch: Safe Browsing V5

Mozilla upgraded Firefox to Safe Browsing V5, including Local List Mode. It replaces the older V4 system and improves protection against sketchy sites without hurting performance.

Custom Keybinds

This update also sneaks in an experimental feature gamers will love: customizable keyboard shortcuts. You can:

• Replace awkward default shortcuts

• Fix conflicts with other software

• Create your own keybind setup

To try it out, type about:keyboard in the address bar. Consider it early-access for power users.
