Modern Chromium browsers (Google Chrome, Microsoft Edge, Brave) use strict site isolation, launching a separate sandboxed process for every active domain, iframe, and browser extension. While this prevents a crashed tab from taking down the entire browser, poorly coded extensions or GPU shader cache corruption can cause massive memory bloat or STATUS_ACCESS_VIOLATION errors.

1. Audit Per-Tab and Per-Extension Memory with Shift + Esc

Step 1: Open the Built-In Chromium Task Manager

While inside Chrome or Edge on Windows, press Shift + Esc (or go to Menu (⋮) → More Tools → Task Manager on macOS). Sort by the Memory footprint column to see which specific extension or tab is leaking RAM.

2. Configure Proactive Tab Discarding and Reset GPU Shader Cache

Navigate to chrome://settings/performance (or edge://settings/system) and set Memory Saver to Maximum so inactive background tabs release their DOM heaps after 15 minutes.
