(Whiteboard: [webcompat-source:web-bugs])

Environment:
Operating system: Android 12
Firefox version: Firefox Mobile 153.0

Steps to reproduce:
I'm using the latest Firefox for Android, and I've noticed that browsing performance feels slower than it used to.

The issue is especially noticeable on GitHub. Navigating between repositories, issues, pull requests, and other pages often takes noticeably longer compared to Brave or other Chromium-based browsers on the same device and network.

My internet connection is stable, and the difference is consistently reproducible. GitHub isn't the only site where Firefox feels less responsive, but it's the easiest place to notice the performance gap.

I don't have exact performance measurements, but the slower page navigation and overall responsiveness are noticeable during normal use.

Actual Behavior:
Firefox for Android feels slower than Chromium-based browsers, especially on GitHub
