Don't see 'Tab Groups' feature even after v137.0.1 update? Here's how to manually enable it

Firefox users eagerly updated their browsers following the announcement of native Tab Groups arriving with version 137.0 back on April 1st. This feature promises a much easier way to organize tabs by grouping related ones together. However, even after the subsequent 137.0.1 patch, many are finding the option missing, leading to some head-scratching online.

If you’ve updated but still can’t find the Tab Groups feature, you’re not alone. Mozilla is releasing this new functionality using a “progressive rollout.” This means they activate the feature for small batches of users over time, rather than for everyone simultaneously.

While this strategy helps Mozilla gather feedback and fix bugs before a wider release, it can leave many users wondering when they’ll get the new tools. As user Salamandar3500 mentioned on Reddit, “I find it very weird to have this kind of so highly awaited feature announced, released, but in fact people can’t use it. That feels like a recipe for anger.”

The good news is you don’t necessarily have to wait. If you’re comfortable tweaking some settings, you can manually enable Tab Groups right now. Here’s how:

1. Open a new tab in Firefox.
2. Type about:config into the address bar and press Enter.
3. You might see a warning page about changing advanced settings. Accept the risk to continue.
4. In the search bar at the top of the about:config page, type or paste browser.tabs.groups.enabled.
5. You should see a single preference listed. By default, its value will likely be false.
6. Double-click on the false value to change it to true.

That’s it! You don’t even need to restart Firefox. Once enabled, you should be able to right-click on a tab and see the option “Add tab to new group,” or simply drag one tab onto another and pause briefly to create a new group.

Keep in mind that enabling features this way means you might encounter small bugs that Mozilla is still working on fixing through the progressive rollout process. Some users initially reported minor issues, although the 137.0.1 update seems to have smoothed things out for many. Also, note that you only need to enable browser.tabs.groups.enabled; another flag related to “smart” or AI grouping isn’t necessary for the basic functionality.

So, you can either wait patiently for Tab Groups to appear automatically or jump ahead and enable it yourself using the about:config trick. Enjoy organizing those tabs!
