Tab Limiter Chrome Extension

Limit the number of open tabs globally and per domain to keep your browser tidy.

Tab Limiter is a simple Chrome extension that helps you manage your browsing by limiting how many tabs you can have open — either across all sites or for specific domains. When a limit is exceeded, the extra tab is either blocked or the oldest one is automatically closed.

Key features

Global tab limit

Set a maximum number of tabs allowed across all sites at once.

Custom domain rules

Add domains and set a maximum number of allowed open tabs for each one independently.

Accurate domain matching

Rules match the exact domain and its subdomains (e.g. example.com also applies to docs.example.com).

Two behaviors when limit is reached

Choose what happens when a limit is exceeded: block the new tab (with a notification), or automatically close the oldest tab to make room for the new one. Set the global default and optionally override it per domain.

Optional badge (disabled by default)

Optionally show a badge on the extension icon with the number of tabs you can still open for the currently active domain. Can be enabled in Options.
