How to snooze your browser tabs

Managing numerous browser tabs can strain your system's resources and memory. This article explores how to "snooze" inactive tabs in popular browsers, freeing up valuable processing power and battery life. Snoozing tabs doesn't discard their content; it simply suspends them until needed, improving overall browser performance.

Google Chrome: Memory Saver

Chrome's built-in Memory Saver automatically targets inactive tabs, limiting their system impact. These tabs reload when accessed. To manage this feature:

1. Click the three vertical dots (top right).
2. Select Performance.
3. Toggle Memory Saver on/off.
4. Use the Add button to exclude specific sites (e.g., music players, chat apps) from being snoozed.

Chrome intelligently identifies active tabs (forms, audio/video, screen sharing, downloads) and keeps them active, even without manual intervention. For finer control, consider extensions like Snoozz, offering customizable snooze settings.

Microsoft Edge: Tab Sleeping

Edge's integrated tab sleeping feature automatically unloads inactive tabs from memory, saving up to 85% memory and 99% CPU usage (according to Microsoft). Access this feature via:

1. Three vertical dots (top right).
2. Settings.
3. System and performance.
4. Toggle tab sleeping on/off. Configure visual cues (faded tabs) and inactivity timers.

Similar to Chrome, Edge excludes active media or webcam-using sites. You can also manually prevent specific sites from being snoozed using the Add button. Third-party extensions like Tab Suspender provide additional customization, including idle time settings and battery level triggers.

Mozilla Firefox: Tab Unloading

Firefox's "Tab Unloading" feature automatically activates when system memory is low. It preserves scroll position and form data. Access the feature via:

1. Type about:unloads in the address bar.
2. View resource usage and last access time for each tab.
3. Manually snooze least-recently-used tabs using the Unload button.
4. Disable Tab Unloading entirely by typing about:config in the address bar, changing browser.tabs.unloadOnLowMemory to false.

Extensions like New Tab Suspender provide more user-friendly tab snoozing options.

Apple Safari: Limited Functionality

Safari lacks a dedicated tab snoozing feature. While likely employing internal optimizations, no official documentation details this. Third-party extensions also aren't available due to Safari's add-on restrictions. If this feature is crucial, consider switching browsers.
