Opera doesn't have a built-in merge tabs feature, but you can move tabs between windows or consolidate them manually

Opera treats each window as separate, so there's no single button that combines tabs from different windows into one. However, you can move individual tabs or groups of tabs between windows by dragging them, or you can open all your tabs in a single window from the start. The method you choose depends on whether you're trying to organize tabs you already have open or prevent scattered windows in the future.

The most direct approach is to drag tabs from one window into another. Click and hold a tab's title, drag it to the other Opera window, and release. If you have many tabs spread across windows, this takes a few seconds per tab but works reliably. For a faster result, you can also close one window (which prompts Opera to ask if you want to save the tabs) and then reopen those tabs in your main window.

Key Takeaways

  • You can drag individual tabs from one Opera window to another by clicking and holding the tab title, then dragging it across.
  • If you close a window with unsaved tabs, Opera will ask whether to save them; you can then reopen those tabs in your main window.
  • Opera's Session Manager (accessed through the menu) lets you save and restore groups of tabs, which is useful if you regularly work with the same sets of pages.
  • Using workspaces or pinning tabs can help prevent tabs from scattering across multiple windows in the first place.

Dragging tabs between windows

The simplest way to move a tab from one window to another is to drag it. Position both Opera windows so you can see them side by side on your screen. Click on the tab you want to move and hold down the mouse button. Drag the tab across to the other window and release it. Opera will drop the tab into that window's tab bar, and it will close from the original window.

This method works for single tabs or groups of tabs. To move multiple tabs at once, hold Ctrl (or Cmd on Mac) and click each tab you want to select, then drag one of the selected tabs to the other window. All selected tabs will move together. If you're moving many tabs, this is faster than dragging them one at a time.

Closing a window and saving its tabs

If you have a window with several tabs you want to consolidate into another window, you can close that window and let Opera save the tabs. Click the X button on the window you want to close. Opera will show a dialog asking "Close window with X tabs?" with an option to save them. Click the save button (or "Save" if the option appears).

The saved tabs are stored in Opera's session history. To reopen them in your main window, go to the menu (the three horizontal lines in the top left), select History, then Recently Closed, and look for the window you just closed. Click it to reopen all those tabs in a new window, or open them one at a time from the list. You can then drag them into your main window if you prefer them in a single window.

Using Session Manager to organize tab groups

Opera's Session Manager lets you save named groups of tabs so you can reopen them later. This is useful if you regularly work with the same set of pages — for example, a group for research, another for email and messaging, and another for entertainment. Go to the menu, select History, then Manage Sessions. Click Save Current Session and give it a name.

Once you've saved a session, you can restore it at any time by going back to Manage Sessions and clicking the session name. Opera will reopen all the tabs in that session. You can also delete old sessions from this menu if you no longer need them. This doesn't merge tabs in real time, but it helps you keep related tabs organized and grouped together.

Pinning tabs to keep them in one place

If certain tabs always scatter to different windows, pinning them can help. Right-click a tab and select Pin Tab. Pinned tabs appear as small icons at the left of the tab bar and stay in place when you open new windows or restart Opera. They're harder to accidentally close, and they visually separate your permanent tabs from temporary ones.

Pinned tabs don't merge windows, but they reduce clutter and make it easier to spot the tabs that matter. You can pin multiple tabs in the same window, and they'll stay together. To unpin a tab, right-click it and select Unpin Tab.

Preventing scattered tabs with workspaces

Opera's workspaces feature lets you create separate browsing contexts, each with its own set of tabs and windows. This doesn't merge existing tabs, but it prevents new tabs from scattering across windows in the first place. Click the workspace icon (usually in the sidebar on the left) and select Create Workspace. Name it and choose which tabs or windows belong to it.

Each workspace keeps its tabs isolated, so switching between workspaces is like switching between different browsing sessions. This is helpful if you work on multiple projects and want to keep their tabs separate. You can still drag tabs between workspaces if needed, but the separation makes it less likely you'll end up with tabs scattered across many windows.

Why Opera doesn't have a merge button

Most browsers, including Opera, treat each window as independent. A merge feature would require the browser to decide which window becomes the "main" one and how to arrange tabs from multiple windows — decisions that vary by user. Instead, Opera gives you manual control through dragging, which takes a few seconds but lets you choose exactly how tabs are organized.

This design also prevents accidental loss of tabs. If a merge button existed and you clicked it by mistake, you could lose track of tabs or close a window unintentionally. The manual approach is slower but safer, and for most users, tabs don't scatter across windows often enough to make a dedicated button necessary.

Frequently Asked Questions

Can I drag tabs between windows on different monitors?

Yes, as long as both Opera windows are visible on your screen setup. Drag the tab from one monitor to the other window on the second monitor. Opera treats multiple monitors as one continuous desktop, so dragging works the same way.

What happens if I close Opera while tabs are open in multiple windows?

Opera saves all open tabs and windows by default. When you reopen Opera, all windows and tabs will return to their previous state. If you want to consolidate them before closing, drag the tabs into one window first, then close Opera.

Can I move tabs to a different Opera profile?

No, tabs are tied to the profile they're open in. You can copy the URL from a tab and open it in another profile, but you cannot move a tab itself between profiles. You would need to manually recreate the tabs in the other profile.

Does pinning a tab prevent it from moving to another window?

Pinning keeps a tab visible and harder to close, but you can still drag a pinned tab to another window. Pinning is about organization and preventing accidental closure, not about locking a tab in place.
