How to Add a Site Exception to Edge Sleeping Tabs List

Quick fix: Open Edge → edge://settings/system. Find Save resources with sleeping tabs section. Click Add next to Never put these sites to sleep. Enter URL or pattern (e.g., youtube.com, *.figma.com). Click Add. Edge no longer puts that site’s tabs to sleep. Useful for music sites, live monitoring, web apps.

Edge’s Sleeping Tabs feature saves RAM/CPU by suspending inactive tabs. Some sites need to keep running (music streaming, monitoring dashboards, web apps). Add to exception list to keep them awake.

What causes this need

Sleeping Tabs suspend tabs after inactivity (default 2 hours). Suspended tabs stop running JavaScript, pause media, free RAM. Issues:

• Music streaming pauses when you switch tabs.
• Web app loses state.
• Live dashboards stop updating.
• Real-time chat / collaboration tools lose connection.

Exception list keeps specific sites running.

Method 1: Add via Edge Settings

The standard route.

1. Open Edge.
2. In URL bar: edge://settings/system. Press Enter.
3. Or: Settings (three-dot menu) → System and performance.
4. Find Save resources with sleeping tabs section.
5. Ensure Save resources with sleeping tabs is on (or off if you want all tabs always awake).
6. Under Never put these sites to sleep, click Add.
7. Enter the site URL or pattern:
   • Specific URL: https://app.figma.com
   • Domain: youtube.com
   • Wildcard: *.spotify.com
8. Click Add. Site appears in exception list.
9. For removing: click X next to site.
10. For Sleeping Tabs threshold: adjust Put inactive tabs to sleep after the specified amount of time. Default 2 hours; can be 30 seconds to 12 hours.

This is the standard setup.

Method 2: Common sites to keep awake

For reference.

1. For music streaming:
   • YouTube Music: music.youtube.com
   • Spotify: open.spotify.com
   • Apple Music: music.apple.com
   • Pandora: www.pandora.com
2. For collaboration / web apps:
   • Figma: www.figma.com
   • Notion: www.notion.so
   • Miro: miro.com
   • Google Docs: docs.google.com
3. For chat:
   • Slack: app.slack.com
   • Discord: discord.com
   • Microsoft Teams: teams.microsoft.com
   • Telegram: web.telegram.org
4. For live monitoring:
   • Grafana: your specific URL
   • AWS console: console.aws.amazon.com
   • Datadog: your subdomain
5. For streams / live events:
   • Twitch: www.twitch.tv
   • YouTube: www.youtube.com

This is the common exceptions list.

Method 3: Disable Sleeping Tabs entirely

For more drastic option.

1. If you have many exceptions: simpler to disable.
2. Open edge://settings/system.
3. Find Save resources with sleeping tabs. Toggle Off.
4. All tabs stay active. Higher RAM usage.
5. For very high-RAM PCs (16GB+): not noticeable.
6. For laptops on battery: more drain. Keep enabled with exceptions instead.
7. For chronic web app freezes due to sleep: disable entirely.
8. For productivity: keep Sleeping Tabs on with carefully managed exceptions list.

This is the all-or-nothing route.

How to verify the fix worked

• Specified site doesn’t sleep when inactive.
• Music keeps playing on background tabs.
• Real-time updates continue.
• Edge memory may be slightly higher (no savings for excepted sites).
• Other tabs still sleep normally (saving RAM for them).

If none of these work

If sites still sleep: Exact URL match: try domain pattern instead of full URL. Specific site iframe: parent site sleeping pauses iframes. Exception applies to top-level domain. For corporate-managed Edge: Group Policy may force Sleeping Tabs settings. For Edge with no Sleeping Tabs visible: enable via edge://flags/#edge-sleeping-tabs → Enabled. For pinned tabs: by default don’t sleep. If they do, enable that option. For Edge Mobile: different setting on mobile. For specific tab not sleeping when expected: real-time activity keeps it awake. Last resort: switch browser: Brave, Vivaldi have similar settings.

Bottom line: edge://settings/system → Save resources with sleeping tabs → Never put these sites to sleep → Add → enter URL/pattern. Pattern: *.spotify.com or youtube.com work. Disable Sleeping Tabs entirely for the all-or-nothing approach.
