Block sleeping tabs on specific sites

Supported versions

  • On Windows and macOS since 88 or later

Description

Define a list of sites, based on URL patterns, that are not allowed to be put to sleep by sleeping tabs. Sites in this list are also excluded from other performance optimizations like efficiency mode and tab discard.

If the policy SleepingTabsEnabled is disabled, this list is not used and no sites will be put to sleep automatically.

If you don't configure this policy, all sites will be eligible to be put to sleep unless the user's personal configuration blocks them.
