Browser vendors recognized this scaling problem and introduced integrated controls to keep resource exhaustion in check. The most effective native safeguard is Memory Saver mode, accessible under the browser's Performance settings menu. When enabled, this feature dynamically freezes and unloads tabs that have remained idle for a designated period, retaining only a lightweight state snapshot in RAM.
For aggressive conservation, set Memory Saver to its maximum threshold and enable background tab throttling through internal flags. This throttles JavaScript timers and suspends DOM rendering routines in background tabs after 5 minutes of inactivity. If your daily workflow demands that certain communication tabs, like Slack or email clients, stay synced in real time, add them to the permanent exclusion list. This targeted approach prevents the browser from discarding time-critical WebSockets while keeping secondary research tabs from hoarding active memory.
