Where to Download Tab Session Manager for Your Browser

Updated

Tab Session Manager is available as a browser extension for Microsoft Edge, Chrome, and Firefox. The official site (tab-session-manager.sienori.com) has a Download section that explicitly offers a Microsoft Edge download, and the project's development instructions confirm Chrome and Firefox builds as well. Pick the entry that matches your browser; the site does not list pricing or account requirements, so treat availability as "free to download" only if the store page you land on says so.

Download options by browser

Browser Where to get it What the source confirms
Microsoft Edge Download section on tab-session-manager.sienori.com "Download for Microsoft Edge" is explicitly listed
Chrome Chrome Web Store listing (linked from the project's GitHub) Development instructions describe loading the extension in Chrome, including a dev/chrome build
Firefox Firefox Add-ons listing (linked from the project's GitHub) Development instructions describe loading the extension in Firefox via about:debugging, including a dev/firefox build

The site's headline describes the product as "WebExtensions for restoring and saving window / tab states," so the same core function—saving and restoring window and tab states, with automatic saving—applies across the supported browsers.

How to install from the official site

  1. Open tab-session-manager.sienori.com.
  2. Find the Download heading.
  3. Choose the download matching your browser. The page names Microsoft Edge directly; for Chrome and Firefox, follow the store link from the project's GitHub page (the site links to GitHub).
  4. Confirm the extension appears in your browser's extension list, then open it once to check that saving works.

Expected result: the extension is installed and can save and restore window/tab states, including automatic saving.

Common snags

  • Wrong browser build: a Chrome package won't install in Firefox or Edge, and vice versa. Match the build to the browser you actually use.
  • Developer builds are not the normal install path: the npm run watch-dev and "Load unpacked extension" steps on the site are for contributors, not regular users. Use the store download unless you're developing.
  • Missing companion features: tab group saving in Chrome is handled by a separate add-on, "Save Tab Groups for Tab Session Manager," listed under Tools. If you rely on tab groups, install that too.
  • Large sessions: the Tools section offers "Session Compressor" for compressing Tab Session Manager sessions—useful if saved sessions grow unwieldy.

  • Save Tab Groups for Tab Session Manager — additional extension for saving tab groups in Chrome.
  • Translation — contribute translations via Crowdin.
  • Developing — clone the GitHub repository, create src/credentials.js with a clientId, run npm install and npm run watch-dev, then load the dev build in Chrome (chrome://extensions → Developer Mode → Load unpacked → dev/chrome) or Firefox (about:debugging → Load Temporary Add-on → dev/firefox).

If you only want the extension, start with the Download section and pick your browser; the developer steps are only relevant if you plan to modify the code.
