Tab overload is one of the most common browser complaints. The usual advice — bookmark everything, close ruthlessly — does not address the actual problem: some tabs are open because you are in the middle of work, not because you forgot to bookmark them.
Tab Manager and Session Saver for Firefox takes a different approach.
What it does
The extension lets you save a named snapshot of your current open tabs and restore it later. Each snapshot is a “session” — a set of tabs associated with a named context.

A typical workflow
You are researching a client project. You have 12 tabs open: competitor sites, a Google Doc, two GitHub issues, three reference articles, some bookmarks you need to review.
You need to shift to a different project. With Tab Manager, you:
- Open the extension popup
- Click “Save session”
- Name it “Client A — Research”
- Close all 12 tabs
- Open whatever tabs the new project needs
When you return to Client A, click “Restore session” — all 12 tabs reopen exactly where you left them.
How it differs from bookmarks
Bookmarks are for saving sites you want to return to someday. Sessions are for saving work-in-progress contexts.
The difference: a session captures the exact set of tabs you had open (including their current state), not just the URLs. When you restore, you get back to work exactly where you left off.
Multiple simultaneous sessions
You can have multiple saved sessions at the same time. “Client A research,” “Project spec review,” “Tax documents,” “Weekend reading” — each saved independently, each restorable with one click.
Privacy
Sessions are stored in Firefox’s local extension storage. Nothing is uploaded. No account means no data exposure.
Limitations
- Local storage only — no sync across devices
- Does not capture scroll position or form state
- Not designed for tab organization within a session (the session is just the set of URLs)
