Mozilla has been working on integrating tab groups in Firefox for quite some time. The organization confirmed in May that it was working on a set of features that would allow Firefox users to use features that other browsers, including Google Chrome, offered already.

Good to know: Firefox Stable users may enable tab groups in the browser already. The feature is disabled by default, but it can be activated in less than a minute and with minimal effort. This guide explains how that is done further down below.

Firefox Tab Groups Features

Firefox Nightly users were the first to test the new tab groups feature. It works similarly to that of Chromium-based browsers. You can create new tab groups and place website tabs inside. You may name each tab group and assign a color to it for improved identification.

A double-click expands or collapses the entire group. Tab groups furthermore carry over between sessions, if you select to reload the last session on start of the browser.

How to enable Tab Groups in Firefox

Note: you need to use Firefox 133 or newer, as Tab Groups were introduced in that version of the browser. Select Menu > Help > About Firefox to update the browser to the latest version.

Here is the step-by-step guide to enable Tab Groups in Mozilla's browser:

1. Load about:config in the Firefox address bar and press the Enter-key.
2. Confirm that you will be careful if the warning page is displayed.
3. Type tabs.group in the search field on the page that opens.
4. Activate the toggle button at the far right of the preference browser.tabs.groups.enabled to switch the value to true.
5. Restart Firefox.

Closing Words

Mozilla is not ready to roll out tab groups to the entire stable population at this point. It might not take that long before the rollout begins though, as the feature looks complete, even in the stable version.

The new feature should give Firefox users a productivity boost and close the feature-gap with Chrome and other Chromium-based browsers.
