What Tab Session Manager Can Do for Saving and Restoring Browser Tabs

Updated

Tab Session Manager is a browser extension for saving and restoring the state of windows and tabs, with automatic saving also supported. It fits the case where you routinely keep many tabs open and want a recoverable snapshot before closing the browser, restarting the machine, or moving between browsers. The site presents it as a WebExtension and offers a download for Microsoft Edge; the page itself does not state pricing or login requirements, so treat availability and any account needs as things to confirm on the download page.

Core capabilities

The extension's stated purpose covers three practical jobs:

  • Save the current state of windows and tabs — capture what is open now as a session you can return to.
  • Restore previously saved sessions — reopen a saved set of windows and tabs later.
  • Automatic saving — reduce the risk of losing open tabs when you forget to save manually.

These map directly to common situations: closing a browser by accident, restarting for updates, or switching to another browser and wanting your working set back.

When it is useful

Situation What the extension offers
Closing the browser with many tabs open Save the session first, restore it later
Restarting or updating the system Automatic saving helps preserve the open state
Switching browsers Saved sessions can be restored in the extension's supported browser
Recurring research or project setups Save a session once and restore the same window/tab set

Related tools listed on the site

The page also points to companion tools:

  • Session Compressor — a tool for compressing Tab Session Manager sessions.
  • Save Tab Groups for Tab Session Manager — an additional extension for saving tab groups in Tab Session Manager for Chrome.

If you rely on Chrome tab groups, the second tool is the relevant add-on to check before assuming groups are preserved.

Installing and verifying

The site provides a download for Microsoft Edge. For other browsers, the page does not list a download link, so check the GitHub repository linked from the page for current build and installation options. After installing, the practical check is simple: open a few windows and tabs, save a session, close them, then restore the session and confirm the windows and tabs return as expected. If automatic saving matters to you, verify it by reopening the browser after a normal close and checking whether the previous state was retained.

Development and translation notes

For contributors, the page describes cloning the repository, creating a src/credentials.js file exporting a clientId, running npm install and npm run watch-dev, then loading the unpacked extension via chrome://extensions with Developer Mode enabled (choosing tab-session-manager/dev/chrome) or via about:debugging in Firefox as a temporary add-on (choosing tab-session-manager/dev/firefox). Translations are handled through Crowdin.

The main decision point: if your problem is losing open tabs across closes, restarts, or browser switches, this extension targets exactly that, and the companion tools are worth checking only if you use session compression or Chrome tab groups.
