Modern web browsers like Google Chrome and Microsoft Edge include memory management features (Memory Saver and Sleeping Tabs) that automatically discard background tabs to reclaim system RAM. This guide explains how to prevent tab suspension for critical background tools.
- Goal: Prevent Chrome and Edge from sleeping active background tabs.
- Method: Audio loops and media tab assertions.
- Security: Native performance adjustments.
How Inactivity Triggers Lock Screens
When a browser discards a background tab, it pauses all JavaScript execution, including wake lock timers. To prevent your keep-awake engine from sleeping, you must ensure the tab stays active. Not Idle utilizes minor audio oscillators and active canvas stream loop assertions to convince Chrome's engine that the tab is actively playing media, which blocks automatic tab suspension.
Step-by-Step Configuration Guide
- Navigate to Chrome Settings > Performance.
- Under Always keep these sites active, click Add.
- Type your website domain (e.g.,
alwaysavailable.blogspot.com). - This guarantees that the browser never sleeps the keep-awake engine.
