Chrome 150 fixes the Tab Groups bug, and here is what changed in TMS

When Chrome 149 introduced a regression that silently discarded suspended tabs inside tab groups on every browser restart, TMS shipped a workaround in version 8.1.4. When the same regression reached Microsoft Edge, we addressed that too. We knew from the start that these were stopgap measures, the right fix had to come from the browser itself.

It is now here. Chrome 150.0.7871.47 ships the browser-side patch for crbug.com/522338670. Tab groups restore correctly without any intervention from TMS. We have verified this with a clean restart session and multiple group configurations, and everything behaves as expected.

Here is what that means for TMS, and what we decided to do with the workaround code.

If you are using Microsoft Edge and noticed that your suspended tabs inside tab groups disappear or turn into blank New Tab pages after a browser restart, you are running into the same Chromium-level regression that first appeared in Chrome 149, and it is now reaching Edge users too.

  • TMS 8.1.4 has been submitted to the Chrome Web Store and is currently pending review. This version includes a fix for the tab group restore issue.
  • The Chrome team is also working on an official browser-side fix: the patch is under review at chromium-review.googlesource.com. It's a race to see who gets there first!

  • TMS 8.1.4 is now live on the Chrome Web Store. The tab group restore issue is fixed, update TMS and you are good to go.
  • The back-grouped-tabs companion workaround is no longer needed. The repository remains available for anyone who still wants it, but you can safely remove the extension.

If you are using Chrome 149 and noticed that your suspended tabs inside tab groups turn into blank New Tab pages after a browser restart, you are not alone, and it is not your fault.

The post has been updated! (2025-07-05)

  • I have included a note unambiguously stating that you will need to use only the 'src' folder to load the unpackaged extension into Chrome.
  • I have changed the links to the repository and the ZIP file to download. The PR has now been merged with the original repository!

Had I lost hope? I'll admit it, yeah, pretty much completely. So you can imagine how thrilled I was when I finally saw a light at the end of that tunnel.

2021 was a great year for The Marvellous Suspender. Lots of contributions, ideas, bugfixes and even a not-so-healthy dose of Google updates that have put the add-on and all its users in a difficult spot. Today's article, however, is perhaps conclusive unless we find new blood in development and a new starting point to rethink the add-on and bring it into the future, the one necessarily dictated by Google and its Manifest V3.

I didn’t think I would ever write such an article, yet here we are. I want to tell you very quickly who I am, what I do and what is happening to The Marvellous Suspender, an extension for Google Chrome that has suddenly come under the spotlight since Google decided to block and "withdraw from the market" the original The Great Suspender. This article is published in Italian and also localized in English to allow all new friends who have landed here to better understand the evolution of history.

Thanks!
