What merging tabs means in Opera GX

Opera GX does not have a built-in "merge tabs" feature that combines multiple tabs into a single tab. What you can do instead is group related tabs together, close tabs you no longer need, or save multiple tabs as a single bookmark for later. If you are looking to combine the content from two different web pages into one view, that is not something any browser can do — each tab displays one website at a time.

The confusion usually comes from wanting to organize tabs more efficiently. Opera GX offers several ways to do this: tab grouping (which visually organizes tabs by color or label), tab stacking (which lets you nest tabs under one visible tab), and tab sessions (which save all your open tabs to reopen later). Each of these solves a different problem.

Key Takeaways

  • Opera GX does not merge tabs into a single tab, but you can group tabs by color or label to keep related ones together visually.
  • Tab stacking lets you click one tab to reveal a stack of nested tabs underneath, reducing clutter on your tab bar.
  • Saving your current tabs as a session preserves all open pages so you can close them and reopen the whole group later.
  • If you want to save multiple pages to revisit together, use bookmarks or bookmark folders instead of keeping tabs open.

How to group tabs by color in Opera GX

Right-click on any open tab. A menu will appear with several options. Look for "Group tabs" or "Add to group" — the exact wording depends on your Opera GX version. Click it, and you will see a list of colors or group names. Select the color you want, and that tab will be labeled with a colored bar or background.

Repeat this for every tab you want in the same group. All tabs with the same color will visually cluster together on your tab bar, making it easier to see which tabs belong to which project or task. You can rename a group by right-clicking the colored section and selecting "Rename group" if your version supports it. To remove a tab from a group, right-click it and select "Remove from group."

Using tab stacking to hide tabs under one visible tab

Tab stacking is different from grouping — it actually hides tabs under a single visible tab. To stack tabs, drag one tab directly on top of another tab. You will see a small number appear on the tab, showing how many tabs are stacked together. Click that tab to see a dropdown or popup showing all the stacked tabs inside.

This is useful when you have many tabs open but want to reduce the visual clutter on your tab bar. For example, you might stack all your email, calendar, and note-taking tabs under one visible tab labeled "Work." Click the stack to switch between them without opening new space on the tab bar. To unstack a tab, drag it out of the stack and drop it on the empty tab bar area.

Saving all your tabs as a session for later

If you want to close all your tabs now but reopen them together later, save them as a session. Go to the menu (the three horizontal lines in the top left), then select "Sessions" or "History," depending on your version. Look for an option to "Save current session" or "Save tabs as session." Name the session something you will recognize, like "Research Project" or "Shopping."

When you want to reopen all those tabs at once, go back to the same menu, find your saved session, and click it. All the tabs will reopen in the same order. This is more practical than keeping dozens of tabs open, which slows down your browser. Sessions also survive if you close Opera GX and reopen it later — your saved sessions stay in the menu.

Using bookmarks instead of keeping tabs open

If you are trying to keep multiple pages together because you plan to revisit them as a group, bookmarks are a better solution than tabs. Highlight all the tabs you want to save, then right-click and select "Bookmark all tabs" or "Bookmark open tabs." Opera GX will create a new bookmark folder containing all those pages.

Later, you can open the entire folder at once by right-clicking the bookmark folder and selecting "Open all." This is faster than manually opening each tab, and it does not clutter your browser while you are working on something else. You can organize bookmark folders by project, topic, or task — for example, "Home Repair Research" or "Trip Planning."

Why you might think you need to merge tabs

Most people look for a merge feature because they have too many tabs open and want to reduce the visual noise. The real solution is not merging, but organizing and closing. Ask yourself: do you actually need all these tabs open right now, or are you keeping them open out of habit?

If a tab contains information you might need later, bookmark it instead of leaving it open. If a tab is part of a task you will return to tomorrow, save it as a session and close it. If a tab is just a reference while you work on something else, use tab grouping or stacking to hide it. Each of these approaches solves the actual problem — too many tabs competing for your attention — without trying to do something browsers are not designed to do.

Frequently Asked Questions

Can I merge two websites into one tab so I can see both at the same time?

No. Browsers display one website per tab by design. If you need to see two pages side by side, open them in separate windows or use a split-screen tool outside the browser. Some websites offer a "pop-out" or "floating window" feature that lets you view part of the site in a separate window while keeping the main page open.

What is the difference between grouping and stacking tabs?

Grouping organizes tabs visually by color or label but keeps them all visible on the tab bar. Stacking hides tabs under a single visible tab, reducing clutter. Use grouping when you want to see all your tabs at once but organized by category. Use stacking when you want to hide tabs temporarily but keep them straightforward to access.

If I save a session and then close Opera GX, will my tabs still be there?

Yes. Saved sessions are stored in Opera GX and will remain in your Sessions menu even after you close the browser completely. You can reopen them anytime. However, if you close a tab without saving it as a session first, it is gone — so save sessions before closing tabs you might want later.

Can I merge tabs from two different windows into one window?

You can move a tab from one window to another by dragging it. Click and hold a tab, then drag it to a different Opera GX window. This is not merging — you are just moving the tab — but it accomplishes the same goal of consolidating tabs into one place.
