Put tabs to sleep
A sleeping tab gives back the memory its page used. It stays in the panel, dimmed, and loads its page again when you select it.
Your Work Workspace has a group of 20 Codeberg tabs you won’t read again until Monday.
- In the panel, right-click the tab or the group, then choose Put to Sleep.
On a group, every tab inside it goes to sleep. The tab you’re viewing hands over to another tab first.
Details
Section titled “Details”- A sleeping tab’s row is dimmed, with a gray icon.
- A page that asks before you leave it, for example one with text you haven’t sent, asks before it goes to sleep too.
- Put to Sleep skips tabs you’ve set to Keep Awake. It’s dimmed when there is nothing to put to sleep.
- A sleeping tab keeps its place and its history. Its page reloads when you select it.
