How to group tabs in Firefox step by step

If you often have dozens of tabs open in your browser, you've probably thought more than once that you need a decent way to organize them in Firefox . Until recently, Mozilla's browser lagged behind Chrome, Edge, and Safari in this area, but things have changed: today it's possible to use native tab groups in Firefox and, in addition, continue to use powerful extensions if you want to take it a step further.

In this guide, we'll take a detailed look at how to group tabs in Firefox step by step , what options the browser's new official feature offers, how to enable testing from about:config, what alternatives you have with add-ons like Simple Tab Groups, and how these new features fit in with other productivity features in Firefox itself. You'll also see why organizing your tabs makes all the difference when working with multiple windows simultaneously.

Why grouping tabs in Firefox is worthwhile

Before we delve into the menus and options, it's worth understanding the benefits of using tab groups. When working with many pages simultaneously, it's easy to end up with an endless row at the top of the browser and waste precious time searching for each specific tab . Tab grouping solves precisely that problem.

The first thing you'll notice is a huge improvement in the visual organization of your browsing session . Being able to group all the tabs related to the same project, theme, or client under a single label means you can see what each block is at a glance, without having to look at each icon individually.

This organization also brings with it an increase in the overall order of the Firefox tab bar . Instead of having everything mixed together—email, social media, online documents, work tools—you can separate each group of tabs according to what you're currently doing, reducing visual clutter and improving concentration.

Another positive consequence is that it can improve overall system performance when managing a large number of tabs . While groups alone don't close tabs, structuring them makes it easier to decide which groups to close or store, preventing the accumulation of unnecessary pages that consume system resources.

Finally, there's a clear impact on daily productivity when you browse with Firefox . By knowing exactly where your work tabs, leisure tabs, and reference resources are, you spend less time mindlessly jumping between them and more time focused on the task that truly matters.

Firefox native tab groups: current status and activation

Mozilla had been receiving requests from users for some time to add a tab grouping feature similar to that of other browsers. After listening to feedback through Mozilla Connect and other community channels , the company has begun integrating this feature directly into Firefox.

Currently, the tab groups feature is being rolled out in the latest versions of the browser, and its behavior is quite similar to what already exists in Chrome . However, for some time it has been necessary to manually enable it from the advanced settings, and depending on the specific version you use, it may still appear as an experimental feature.

When Mozilla releases something like this, which hasn't yet been fully integrated into the final stable version of the browser , it's to polish the details. This means that, although it's already usable, it may still have bugs, exhibit strange behavior, or have variations between versions. Keep this in mind if you decide to enable it manually.

For those who can't wait, the way to try this feature is to first make sure you're using Firefox 133 or a later version . This is a key requirement, because in earlier versions the necessary setting doesn't even appear in the advanced settings panel.

Once you've verified the version, you need to access the internal configuration page. This is Firefox's famous "about:config" screen , where the browser's experimental and advanced settings are located, many of which still lack a graphical interface.

How to enable tab groups in Firefox from about:config

Manually enabling the tab group feature in Firefox, as we mentioned, involves accessing the advanced settings panel. First, type about:config into the address bar and press Enter in Firefox . The browser will display a standard warning that you are about to modify advanced preferences and advise caution.

After accepting the notification, you'll see a search box at the top. Enter the exact name of the preference "browser.tabs.groups.enabled" there . This entry controls whether the tab groups feature is enabled in your browser.

By default, this option is set to "false," meaning it's disabled . To enable tab groups, simply click the corresponding switch or icon and change it to "true." This tells Firefox to load the new feature.

After changing the value, it's essential to close and reopen Firefox for the setting to take effect . A simple browser restart is all it takes: when it reopens, the groups feature will be operational and ready to use in the tab bar.

It's worth noting that, as this is a feature in testing, you might notice unexpected behavior or minor bugs , especially if you use other plugins that also manage tabs. If something doesn't seem right, you can always go back to about:config and set “browser.tabs.groups.enabled” to “false” to disable it again.

How native tab groups work in Firefox

Once enabled, using tab groups in Firefox is quite intuitive. The experience is similar to Chrome: you can create groups by dragging and dropping tabs on top of each other . The moment you drop one tab onto another, the browser automatically creates a group.

When you create this group, the Firefox interface lets you assign it a name and a distinguishing color . These two elements will help you quickly recognize it in the tab bar, especially when you start managing several different groups in the same window.

In addition to the name and color, you can collapse or expand each group by clicking its color button . When collapsed, you only see the label with the name and color, saving space and reducing visual clutter. Expanding it reveals all the tabs belonging to that group.

If you want to rearrange your tabs, simply drag them from one group to another with your mouse . The system works much like other browsers: when you drop a tab within the group's visual boundaries, Firefox automatically integrates it.

There aren't too many extra features at the moment, but the essentials are covered: creation, renaming, color assignment, and folding/unfolding . While the implementation might seem somewhat basic to advanced users accustomed to very comprehensive extensions, it's a solid foundation and, above all, integrated directly into the browser without relying on third parties.

AI-powered tab groups: Firefox's smart groups

Alongside the basic function, Mozilla is testing an even more interesting extension: so-called smart tab groups based on artificial intelligence . The idea is that the browser itself will suggest automatic groupings based on the content you have open.

In this approach, Firefox analyzes active tabs and tries to suggest names and groupings automatically . For example, if it detects that you have several pages related to the same topic or task, it could group them under a consistent label without you having to do it manually.

A key detail of this experimental feature is that tab data processing is done directly on the device . This means the data isn't uploaded to Mozilla's cloud or external servers for analysis, helping to protect your privacy while these AI capabilities are being used.

Mozilla's stated goal with these smart groups is to help everyone from those managing just a few tabs to extreme users working with hundreds or even thousands open . In either case, automatic assistance with sorting and categorizing tabs can make a significant difference in ease of use.

Currently, this feature is in the experimental phase and may change over time , but it fits with Mozilla's broader strategy of introducing AI capabilities into Firefox in an optional and controlled manner , always prioritizing user privacy and control over their data.

Firefox's old "Group Tabs" view: how it worked

Long before this new wave of features, Firefox already had a dedicated tool for organizing tabs called, precisely, "Tab Groups" (or Panorama) . It was a special view where tabs were displayed in floating rectangles on a desktop, allowing for very visual management.

This function was accessed by clicking on an icon with four rectangles of different sizes, located near the minimize button , or by using the key combination Ctrl + Shift + E. When activated, the browser changed to a kind of board where each square represented a group of tabs.

Within this view, all the tabs you were currently working with were displayed within a main group. This initial box served as the starting group, from which you could begin distributing tabs to other groups or restructuring your browsing session according to your needs.

Using this old feature relied on very simple mouse gestures. For example, to create a new tab group, you simply had to double-click on an empty area of ​​the desktop —that is, a space where there were no tab boxes. A new, empty group would then automatically appear, ready to receive tabs.

This "desktop"-style interface allowed you to almost play with the tabs, moving and resizing groups at will, and offering an overall view of everything you had open without being limited to the narrow top bar of the browser.

Actions available in the classic tab group view

The old "Group Tabs" view offered a fairly comprehensive set of actions. One of the most important was the ability to delete a group of tabs directly from its box . To do this, you clicked the cross located in the upper right corner of that group.

When you tried to close it, Firefox displayed a small box with the text "Undo close group" accompanied by another cross. If you clicked the text, you canceled the closure, and the group remained as it was. If, on the other hand, you clicked the cross or exited the view, the group was permanently deleted.

This deletion was permanent: once confirmed, there was no way to recover the group or its tabs . That's why the browser introduced this intermediate step, as a safety net, to prevent accidental deletions when working with many tabs at once.

Another useful option was renaming a group to quickly identify the type of tabs it contained . To do this, you clicked at the top of the box, where a small pencil icon appeared if no name was already assigned. Clicking this icon allowed you to type any title you wanted for that group.

In addition to the name, the group view allowed you to adjust the size of each box. To resize a group of tabs, you used its bottom right corner : with a click and drag of the mouse, you could enlarge or reduce it according to your preferences.

As you resized one group, the rest dynamically repositioned themselves to prevent overlapping within the group desktop . This allowed you to arrange them so you could easily see where each set of tabs was located, without any obscuring others.

It was also possible to move an entire group to another area of ​​the groups desktop . To do this, simply click anywhere within the group box (not just the border) and drag it to the new location. Just as with resizing, the other groups would rearrange themselves to avoid overlapping.

To move tabs between groups, the method was equally simple: you could drag a tab from one group to another and drop it . If you dropped it onto an existing box, it would be integrated into it; and if you dropped it in an empty area, Firefox would automatically create a new group containing that tab.

Move tabs between groups and search for them from outside.

Tab management between groups wasn't limited to that special view. From the regular Firefox interface, it was also possible to move tabs from one group to another using the context menu . This was convenient when you were already working on a specific page and wanted to rearrange it without changing views.

To do this, you had to right-click on the tab and choose the "Move to Group" option. Firefox would then display a list with the names of all available groups to choose from . This way, you could reposition it without having to drag anything onto the Groups desktop.

Another interesting feature of that classic function was the ability to search for tabs within all open groups . In the groups view, a magnifying glass icon appeared near the close window button, and clicking on it activated the search box.

Alternatively, the same action could be performed using the keyboard shortcut Ctrl + F. After doing so, you only had to type the text you wanted to locate, for example part of the title or content , and Firefox would highlight the tabs that matched your search within their respective groups.

When you wanted to return to working with a specific group, the process was also straightforward: simply click anywhere within the rectangle representing that group of tabs . If you clicked on a specific tab within the rectangle, the normal view would open with that tab already selected.

To exit the group view, there were two main ways: press the Escape key on the keyboard , which returned the window to its previous state, or use the four rectangles icon again, which in that view appeared below the close window button.

Pinned tabs and groups: how they behave

One curious detail about the old "Group Tabs" tool was how it handled pinned tabs. These are the tabs that are always anchored to the left side of the bar, typically for services you use frequently, such as email or a web application.

Within the context of groups, pinned tabs behaved in a special way: they remained visible and active across all groups . In other words, even if you switched between boxes or sets, those pinned tabs remained available without moving from their position.

Within the tab group view, these pinned tabs appeared in the right margin of each group, separate from the rest . This behavior made them very convenient for keeping, for example, a control panel, a music player, or a messaging tool readily accessible, regardless of the group you were working in.

This approach reinforced the idea that groups were mainly used to organize temporary or thematic work tabs , while pinned tabs were understood as a kind of basic infrastructure that accompanies your entire browsing session.

Although Firefox's current implementation of tab groups differs from the classic view, many users remember the flexibility to combine groups and pinned tabs as one of the system's great strengths, and Mozilla is likely to take these experiences into account in its design decisions.
