📁 Middle-click any tab, group, or workspace to unload it and free up memory
📁 Search every workspace at once and jump straight to the tab you meant
📁 Undo and Redo your sidebar changes, like closes and moves
📁 Snapshots save your whole setup — on a schedule or whenever you want
📁 Import your bookmarks into a workspace, with a group for each folder
📁 Optional Firefox container support, with a default container per workspace
📁 Make it yours: 40 icons plus your own images, colors, gradients, and four sizes

Terminus lives in your Firefox sidebar. A narrow rail of workspace icons sits beside your tabs, and clicking a workspace swaps your whole tab set in one go — the tabs you leave behind aren't closed, they're just hidden, exactly where you left them when you come back. Each window remembers its own workspace, even after a restart.

The part you'll stop thinking about (in a good way) is snapshots. Terminus can quietly save your workspaces, tabs, and window layout on a schedule, and one automatic snapshot from before startup is kept safe until you delete it. Restored tabs come back unloaded, so even a giant snapshot opens without loading a thousand pages at once. Restore everything, one window, or just the tabs you pick.

And a promise: Terminus has no account, no server, no sync, no ads, and no analytics. Your tabs are your business — everything stays in your Firefox profile, it never reads the pages you visit, and the only thing it ever downloads is a website's icon. The privacy policy spells out every permission and why it exists.
