Websites these days can be big and use a significant amount of resources. Closing tabs is a good way to reduce memory use, but what if you need to keep the tabs around and don’t want to close them? Hibernating tabs is a good alternative to both keep the tabs open and reduce the browser’s memory usage.

To hibernate a tab:

1. On the Tab Bar or in the Window Panel, right-click on a background tab or Tab Stack.
2. Select Hibernate Tab from the context menu.

To hibernate all background tabs:

1. Right-click on any tab on the Tab Bar.
2. Select Hibernate Background Tabs from the context menu.
